ok, I just bought a set of 416's. They have this work done to them.
Premium castings inspected then baked and blasted using a new AMPRO cleaning system. This cleaning system is over $50,000 so don't settle with a 100 year old method of jet washing. THESE HEADS ARE CLEAN!!

The cleaned castings are then inspected and magnafluxed for any hidden flaws

The heads are then put on a DCM seat machine where the valve areas are cut open to accept a 2.02 intake and 1.6 exhaust. The valve areas are bowel hogged out to improve the air flow. (this does not mean the runners are ported) We unshroud the area near the valve head to IMPROVE air flow. The guides are replaced with BRONZE guide liners to assure long life. The valve seats are cut with 3 ANGLE cutters to assure the valve job is done properly.

The heads are surfaced on a Storm Vulcan surfacer using CBN cutters. These cutters are the size of a dime and run $220 per cutter. Expect the BEST finish in the industry. (I didn't tighten one down once and the little bugger flew accross the shop. Searched for 3 hours and gave up. Then had a beer to feel better, didn't work)

The heads are assembled by a EXPERIENCED machinist.

Painted and bagged to keep out any dust or dirt.

PARTS USED IN THESE HIGH COMPRESSION HEADS

All new bronze valve guides. By K-Line

.510 lift valve springs. By Elgin

NEW hardened race valve spring retainers. By Elgin

New performance spring keepers. By Pioneer

I also had them machine them for screw-in studs and guide plates,wich he is also supplying.

I am looking at the Crane Powermax cam and lifter kit wich is...

302/302 480/480 lift.


Here is my question..will this cam work well with my 327 and a 22-2500 stall? Also, As for the rockers....should I go with the roller-tip rockers? would there be much of a gain? Or could I use the stock rockers. I know I will need the hardened pushrods. I have a performer intake, Headers, 600 edelbrock carb...I guess what Im asking is what other parts besides gaskets do I need to look at changing...I currently am running 462's..and no acc. holes....help me out here guys..thanks

Yeah I've seen that guy on e-bay too, definitely gives good ink, don't know much about his heads though....

Definitely don't use stock rockers. If you don't already have them, get him to cut them out for 1.45" springs, and use roller (or at least roller-tip) rockers.

With a small motor and that much cam, it will be a total pig off the line with that little converter. You should be looking in the 3200-3400 RPM range. Get a good trans fluid cooler and bypass the stock one.

Thanks for the reply Rb, Here is the deal.....I just bought a 94 z28. LT1 T-56 combo...ran me $8700..great buy for a great car....but the wife drives it. Now I have about a grand left to get my 89 back on the road. The bottom end of the motor is tight , the old 462's are shot. I bought the new 416's after talking to the guy on the phone. He seemed to know his stuff and was great to deal with so far....$500 with the studs and guide plates...done deal.
Can you suggest a cam ...comp or Crane that would work well with my set-up...here it is....327 .030 over flat-top forged pistons. performer intake 600cfi edelbrock carb. Headers and 3" exhaust. 700r4..Vette stall...3:42 geaRS AND THE 416 HEADS. I have another $500 to spend. Heads and valve train are not my topic. I want to make more Hp than the stock 94 LT1 at 275.
What would you do?

Riley's35089rs+

comps XE274H.......this I think Will work much better, So I would guess I would go with the 1.5 roller tips?

I'd finish the job they started by completly porting the heads.
I'd use a 3500 stall converter and 3.73+ gears.
I'd switch to a Performer RPM intake.

The rest sounds good. Good luck...

Riley's35089rs+

Thanks for the reply F-Bird. Sure I have a 3000 Stall converter, only problem is it's for the early model 700r4, junk. I have 2 1/2 27 spline 700r4's in my shed...shredded....2 by the car, 1/2 by me.
I bought an 87 Tranny with a new Vette stall, I realize they only run maybe 500 over stock, But it is all I have at the moment. I can swing the new intake, The gears I hoped to do this summer anyways, As for the porting, I'm a chicken!!! And 3-$600 is out of my budget right now.
So, will I be streetable? Will the car perform with the mods I have plus the rpm intake? Guess I'm gonna find out. If not, Ive had the tranny in and out so many times, I think I can do it in the dark. I just want to wait until I can afford a "good" stall. Ive had experience with the $250 POS......
Thanks again for all your help, you 2 guys are a great resource and I am greatful....:hail:

P.S
Hope you are around in March when I start this Swap....I'm going to need ALOT of help..

I guess it doesn't help much to say "Don't worry, you can do it." But it is true. Porting, bowl-blending and polishing is a SLOW business and it is REALLY HARD to make a serious mistake. Iron is just too hard to cut through like butter.

Pay attention and you will be rewarded with both a great experience and hp that you will feel every time your foot goes to the floor

F-BIRD'88

Have to put that converter on your wish list.

But don't be chicken. Grab any old cylinder head and practice a bit to learn to control the grinder.

It's not real hard. well worth the effort thou.
If your going to grind on the chamber get two old valves to set in there to protect the machined seats while working.

sears sells the best bang for the buck electric die grinder.

look in the industrial catalog, model 2144 or something like that.

You don't recommend touching the valve guide much, huh?

I was reading a book about porting heads (I think written by a european, as all the heads he ported were for old inline 4 cyl engines that I'd never heard of) and the author recommended grinding the valve guide flush with the port roof. The "After" pics of the heads looked odd to me, with no protruding valve guides.

Whattya say, F-BIRD?

12secRS

That's a pretty good cam for a 327, I ran it in a 12:1 327 with 200 cc pro topline heads and a performer rpm intake with a 750 VS carb, 4.10 gears and ran 12.35 @ 112 mph in my 89 rs

F-BIRD'88

Yes you can shorten the valve guide that protrudes into the port
and slim and streamline it. It will improve flow a lot.
just keep in mind that the valve guide supports the valve in the head. The shorter it is the more concentrated the side forces
are ( guide wear.) I like to shorten it by about 50% or so.
But I don't totally remove it. If I were building for a NHRA Superstock motor that doesn't have to last, I might.

Guess I should fix up the diagrams eh...

NTChrist

Poifect, thanks.

Yeah, that vertical red line in the diag. made me think that you didn't shorten the guide at all. Good points about the guide walls, tho.

When I get into the meat of the porting, I'm going to have to set my heads at your feet for inspection occasionally.
:hail:

F-BIRD'88

Ya right,,,, LOL ok


here's the fixed up pic I like to shorten it to just where it meats the bowl on the back side of the guide boss.

Riley's35089rs+

The Yank or vigillanty are on the top of the wish list...
12secRS..sounds like a great combo you had there...I know this 327 would love 4:10 gears. I hope to do just that this summer. Gotta get that overtime rolling.
I may attempt to port these heads myself. I could practice on the old 462's, they aren't worth a whole lot more. I have a good didgital camera, when the heads arrive , I'll post some pics and you guys can help me out.
Sitting Bull, That thread you have in your sig is great, Guess I may have to add another..
Thanks again guys, we'll be talking!

Better pictures here http://www.sa-motorsports.com/diyport.htm. Just happen to be 416 heads to boot.

Those instructions are included in poster form when you get their Deluxe Porting Kit. I hung it over the bench while I was doing the work.

Sitting Bull

Alright! That's the spirit!

Seriously, those of us who have taken the plunge into F-Bird'88's 305 porting project are stupefied by how well the heads work AND the fact that ANYONE can do it!

I really do wish that everyone on our board here would do up a set of 305 castings just for the experience of how easy it is and how well they work
