Ok, Ok, i know afr is going to come up, but what about the others? I'm looking at a set of the jegs SBC alum. heads- they have some pretty good numbers... http://www.canfieldheads.com/sbc_2500.html 1298.98 a pair, assembled with valves big enough for the roller cam i am gonna be running. also, i'm looking at a set of trickflow heads- 1345.95 a pair. Specs- TFS-30400007-CNC 1987-95 non-LT1 350 A356-T61 Aluminum CNC-Profiled 64cc chamber 195cc intake volume 75cc exhuast volume 2.02 in. Intake, 1.60 in. Exhaust 1.46 in. Double Springs with Dampers 7 Degree, +.050 in. Machined Steel Chromemoly Steel ARP 3/8 in. 5/16 in. guide plates for Hardened Pushrods here's the flow numbers side by side for comparison: ..............Trickflow CNC chamber..............Canfield ...............INT...................EXH................INT.......EXH .100.......64.2..................55.9................72.........53 .200......138.5................105.2..............145.......107 .300......197.7................145.5..............201.......143 .400......237.1................170.7..............247.......175 .500......256.8................186.3..............258.......190 .600......258.4................195.9..............259.......200 Now, something intresting to note, is that canfield claims these to be the flow numbers at the same specs, but with some mildly bowl blended ports... Anyways, which ones would you folks go with? I don't have the cash to have afr or someone else mill down there heads to 64cc, and slap a set of bigger springs on for the roller cam. My goal is to get 475hp, 450trq out of this motor with this cam(flywheel) CompCams XR288HR Lift- .520/.540 w1.5 RR's Dur @ .050 - 236/242 LSA- 110 I plan on running a victor intake with this motor, its a zz3 shortblock. for all those that doubt the Edlbrock etec heads, with the XR282 cam (dur@050- 230/236, lift- 510/520, lsa110) with a spring swap (the springs that came with them weren't enough)on top of a ZZ4 short block, we made 450hp, 430trq at the flywheel on the dyno... 750 carb, 1 3/4 shortie headers. Great under the curve numbers too. heads were untouched except for the springs I am kinda leaning towards the tricflows right now- i have a set on hold at summit, so i need to make the decision soon! Steve

I would vote for AFR, though I went with 88 and up corvette heads But even with all the porting on my heads they will not flow as well as a nice set of 195's (which you will most likely need to hit your goals).

However for a fully ported, gasket matched, polished, and rebuilt with lt4 hot cam kit, set of heads I couldn't go wrong for $600.00.

Save your money if you are going to drop that kind of change and get the AFR's. If you are going to do something you might as well do it right the first time.

87IROC are you talking to me or fb305?

If your talking to fb305 he already has the money for AFR's if he is talking about $1,300 for trickflow's.

If your talking to me, driving my car is much more important than waiting to save up an additional $1,300.00, only to have them go into the machine shop to be ported again, and readied for my car. As well as looking at the 8-10 week turn around for AFR's right now. Plus I am not looking for 475hp. 300rwhp will be just fine for me, and stock the vette heads are rated for 350 with a mild porting 380, and a heavy porting 425. MORE than enough for me and my super rammed 383.

I think AFR is the best but I went with Canfield just becaurse I had to wait 12 weeks for AFR heads......

/N.

i know the afr's are great heads, but are they wroth the 1300 bucks for the pair, plus 200 bucks to get them decked to 64cc, plus 200 bucks for the roller cam spring upgrade???


thats 1700 bucks, not 1300....

i am really lookin for experiance with the trickflow and canfield heads- i know the afrs are good!

anyone with any thoughts/opinions on the Holley SysteMaxII alum heads?

I have never heard a bad thing about the canfield heads. I think a new set, that is built, and you have some extra porting done to, should outflow out of the box AFR's (remember I said out of the box) and will be under the price you are looking to pay. From what I hear that $800.00 jegs heads are canfields.

I paid 1450 for my AFR's about 8 months ago. That was with extra for titanium retainers and center bolt valve covers. I'm running .544 lift with a CC-305 cam, and over 6K with no problems. Of the 2 heads you specified above, I'd go for the Canfields.

I'm really happy with my E-tec 200 vortec alum. heads... I've got those, with a performer rpm vortec intake and a edelbrock eps-800 carb... The throttle/tv cable bracketry has been a pain, but I'm gonna try that www.tvmadeez.com system and see what happens... but the heads rock!!

no mention of BRODIX c'mon guys

I think considering brodix, TFS, and AFR are all in the same price range, and considering the fact that AFR outflows everyone, it makes it very difficult to choose anyone but AFR. But than again I didn't

If I went with a Victor Jr./ w/carb, I would have 2 choices.

1. Dart Pro-1 (over 300cfm out of the box)

or

2. Brodix cnc ported track 1 - 23*'s (also over 300 cfm)

Hey 1bad what kind of HP are you putting out? That is almost (minus the vortec stuff, going super ram) that I was looking at. Wanted to see what kind of numbers I could be hitting.

James

What about the edelbrock aluminum heads??

I don't think many people back edelbrock on much of anything anymore. I think they are still living off glory days the way most people talk about their stuff, but I have never had any problems. They just seem to be a good replacement for stock, but if you want real power, you have to step up.

James

check out the dart Pro 1's or even the iron eagles for that matter.

I don't think "Iron eagles" can be used when asking for the best aluminum heads

Well I did mention the Pro 1's first. Besides, with the right work, The Iron eagles will flow as good as some of the aluminum heads. They are also cheaper. also Depends on compression ratio you are looking for..

I still like the 8113 D port exhaust vette heads for cost, reliability and street power. For example:
I bought a pair for $350.00 shipped, used of course.
I bought a lt4 hot cam kit for $215.00, all the parts go onto the vette heads, plus I get the cam!
So let's say I paid $125.00 for the cam.
I am now looking at $95.00 for lt4 springs, retainers, locks, you name it.
$250.00 for port work, gasket matching, and building the heads and for less than $700.00 I have aluminum heads that can easily support 425 hp. No where near the other heads, but plenty for me.

James

i'm not looking to build a motor that makes its power between 6000-8000rpm, and i certainly will never need 210cc intake heads... just WAYYYY too much for a 350... 383, pushing it, and a 400, well prolly be ok for a 400....


i went with the trickflows- thye had good numbers. Close to atfr's too. The thing with the canfields that i didnt like was the fact that they posted flow numbers after mild bowl blending.... not out of the box form.

I had a set of trick-flow 23's (I sold them before they even went on a motor). On the bench they only flowed 243 cfm at a .600 lift, 238 at a .500 lift. They had REALLY bad cast flash that needed to be cleaned up. If you are serious on these heads, be prepared to dump a few more $$$ into them for some mild porting and polishing, then they will flow that 250 - 260 that you are looking for.

My vortecs flow in the 270's which was plenty enough for my intake/cam that I chose.

Jstcrzyengh - I should be able to have the car dyno'd soon. I'm figuring arround 425-450 hp and 450-475 ft.lbs at the crank. I still have a few more things to do before I dyno it though. If you want to read my progress, goto my post "I finally got all the parts needed to finsh the motor".

Mike (1bad91Z)

Thing with the Trickflow is they only CNC the chamber. AFR CNC machines the ports. Virtually guarantees every head and every runner will be as close to exact as possible. Hard to go wrong with any of them though.

hey 1badz what forum? TPI?

James

It's in this forum (Aftermarket Product Review)

i have a die grinder, and the correct bit you can be rest assured i will be doing some porting on them

we'll see, i'll update the post on the trickflow heads and see how they are. i should be getting them tonight!

you better get your pushrod length right.. those trickflows are tricky! hence the name!

Yeah i have the tool- they give a recommended pushrod size for stock hydrolic roller blocks/lifter setups, i'll start there with the tool and see how it goes.

As for the heads, i got them today, and while obviously they are not cnc'd in the ports, there is next to nothing for flashing, and the chambers are beautiful! i have a sanding/polish kit, i will be puling the valves out and smothing everything out nice. I really dont see much room for improvement

the build quality seems to be great! i will hopefully have dyno charts up with in a few weeks... gotta get the money to engine dyno it

I have my sales slip from AFR right here - $100 to mill my 195's to 64cc. Who quoted you $200?

they did actually, over the phone

What the h*ll is this? ^

somebody spammed the board last night

I'm surprised nobody brought up Pro Actions yet. They have numbers very close to AFR's and are alot cheaper. Be prepared to wait though. I'm going on 6 weeks for mine.

GM LT4's

Well, if talking gm, and were talking LT's... than I got to go with lt5

Would the LT4's not require a diffrent block, or atleast waterpump?

That was kind of my joke, about the lt5's from a zr1. You would need an external thermostat, NO EGR, and a few other unpleasant things, but nice gains, I guess.

That and the fact that the starter is underneath the intake, I believe. But an Lt5 swap would be unmatched.

I like my GM fastburns. From what I understand, they're very similar to the Edelbrock (I won't admit to having their stuff on my car!) E-Tec heads, which I also hear decent things about.

^^^^^^^^^^^
That crap is getting really annoying! I wish those scum suckers would all have their computer systems crash to never be restarted! Better yet, let their cars run on windows! LOL

Dude, It's gotta be some 12 yr old punk trying to show his puberty! Anyway, AFR's are the way to go! Trickflow's are ok but the craftmanship suck! Canfield's are great too! Dart's are another good option, but why pay 1000$ when for a little more you can have the very VERY best?

I will be another to say the Edelbrock E-tec 200s are definitely worth looking into. I think the price most likely went up on these now but when I was looking into them they were just under $1000 a set and from what I remember flow as good as the AFR 190s for a bit less money.

i guess i'm not seeing where you guys are getting off saying the craftsman**** sucks on them-

the ports might not be cnc, but the casting is great, there is NO flashing...

oh well it will be intresting to see the dyno numbers

Im with fb305svs my trickflows were the same as his no flash the ports are pretty smooth too.

eman- what kind of setup are you running? any et's or dyno numbers?

No times or dyno pulls yet Im still working out some little bugs.Also right now Im running a 750 edelbrock carb and stealth intake not the Stealth Ram.

hmm sounds likes a decent setup- should be intresting to see what you put down for power...

i'm runnin a zz3, comp cams xr288 cam... - 236/242 dur 520/540 lift, 110 lsa

I should have went with the comp 230-236 cam or the one your using the Hot cam is kind of mild in the 383.Once I get all the little bugs out Ill post some dyno #s and time slips.

The hot cam is mild? I guess maybe in a 383. I am kind of happy to hear that, because I am looking for excellent daily driver ability. 350rwhp would be just fine for me.

sounds good man- i dunno if i will have the tranny to hold th epower yet, so i might have some granny shift slips for y'all i a few weeks
