Okay guys, what would be a good / better set of heads to use on a 350 TPI motor ?

Currently have a 305 TPI setup and looking to go with 350 or 383 and TPI. Any recommendations ?

 

first off which are you wanting to do 350 or 383 big difference there second what are you wanting to do with the car and what is your current setup both motor and otherwise on the car and probably most important is budget

 

Probably stay with 350.
The car with a nice llittle street warrior.
No limit on budget but don't want to spend what the motor build will cost me on just heads !

 

AFR 180cc

Price tag at $1450 - $2000..... I don't think so !

I guess I need to do some brushing up on my SBC info.... I can get a nice set of DART's for a heck of a lot less !

 

And prolly have less power for the money.

I would go with 210s but no smaller than 195s. I ran them on several tpi 350s and they made more power everywhere than smaller heads. You will need a big base and big runners to make it work like it should. Look into the FIRST intake if you want even more.

Prices on everything have gone out of control..

 

Edelbrock's E-street heads are cheap compared to AFR's.

 

The better performing head will always cost more
You wont get "same as" for less money just never happens

Pick accordingly.

 

why not got with vortec heads...?

 

Lol

Honestly I have a set of Dart Iron Eagle 200cc heads and they make some descent power on a 355... especially for what I paid lol. I have a 2,200 converter in the car though so I can't say what they'd do down low.

 

Like anything else if the rest of the system is up to the task of moving air ie intake exhuast etc you will notice more difference from the better head. If not then- Good stuff costs money

 

Thanks for all the replies.... We're talking small block chevy here. SBC parts and pieces are inexpsensive.

I'll just get myself re-aquainted with the SBC parts world again.

 

GM has a 210CC intake runner fastburn head thats a decent price and based off of the vortec head. It requires a special intake tho.
I have 1 new in box fast burn and a Vortec TPI base for the heads. PM me if intrested.

 

for cheap performance heads the vortechs are hard to beat but are cam limited for a strictly street car it is not that hard to work with from what ive read but for good new performance the profiler heads are really good too also from research ive done and cost a lot less than afr's but also depending on what you want to spend gm puts zz4/113 heads on a lot of crate motors and they do well

 

Aftermarket aluminums will run 900-1550 for 180-200cc ranges. Thats way it goes.

Some irons are in similar price range. I like aluminum for weight savings. Usually better heads since everyone is making an aluminum casting and not many irons available. Easier to work with and machine if you ever need to work on them.

With heads i would go aftermarket tpi base and runners. You will have 700-1000 in that new. Used can find parts for less. I would not do heads and keep stock intake on it. Even stock iron L98 headed motors make substantial gains with upgraded intake manifolds, so more head flow wont help much with big intake restriction on top

 

Question???.Where is the power made??.

That is assuming it is on a sound bottom end too!!!.

 

very true to a point the heads are a huge part followed by the cam but the whole thing has to work together mismatched parts are a quigk way to nowhere

 

just dont want anyone too caught up on one thing spending money they wont see returns from

 

NOT on a $2000 set of heads.

 

Afr's are only 1450 from most places for street ports. You dont need or want the comp ports. And yes they do make power but they arent for everyone or every combination

 

^^^
Comp ports not needed.

Too bad you didnt have more budget
AFR came out with a 190cc Vortec head that looks fantastic on paper would love to see someone use these in a build. Of course wiht the TPI may not take full advantage of them. Still...
What youre wanting to do with your parts, GM Vortecs it will still run good.

 

I was thinking along the same lines. Not looking for anything fancy, this is just a nice street car for my son. Now I just need to do some research on which vortec heads... casting numbers... etc.

This is the latest I've come across:

198 INTAKE RUNNER HEADS WITH STRAIGHT PLUGS
this head fits both conventional and vortec intake manifolds.
64cc chambers
202/160 valve seats

 

If you do vortecs you need the 500$ base to keep tpi or some other sort of vortec intake like stealth ram or something. Scogging dickey and summit sell vortec heads machined and ready to go for 350-600 a set but factor in a intake then it comes out closer to aluminum heads.

But thats ok since you should get new base and runner intake components to make some power. If you went budget aluminum, then you could port the stock tpi intake and upgrade runners and make decent numbers. You got some choices to make depending on your power goals

 

The heads I mentioned above ARE aluminum and accept both vortec and standard intakes.
I also looked into porting the TPI base and buying some aftermarket runners. Heads above, SLP runners and ported TPI base should run me less than a $1500 set of AFR heads.

 

Link to heads mentioned? Sounds like you are on the right track

 

That just means the heads have both bolt patterns.
What they dont tell you is a stock TPI base doesn't work with a vortec intake port because its not big/tall enuff to cover the tops of the intake ports. Soo you'll most likely have to buy a $400ish vortec type base.

 

True, but a nice set of vortec 906 heads is only $450 bucks. And the aluminum heads i mentioned above are $600. I can still get everything i need for less than a high dollar set of AFR's or any other big buck heads.

 

The vortec is a good head, SDP also has a bigger port vortec head for a bit more coin.
Do you have a link to the aluminum heads your looking at?

 

These are the aluminum heads:

Those are bare heads. When you add valves, valvejob, rocker studs, seals, etc to finish off the head you have another 200-400 into them easily.

 

Already have roller rockers, screw-in studs and guid plates from other builds that were left over. I have a GOOD friend with a machine shop that gets me parts at cost and a BIG break on machine work.

 

That would work then. Give them a good look over and put in quality valves amd springs. More work and maybe more money in the end depending on your deals. But you get a custom head

 

With those being 198cc heads, I think that would be pretty good for a nice street motor.

OR

Even a set of 190cc CI vortec's would work nicely a well.

 

198 would appreciate a shorter runner intake like a heavily siamesed slp runner or other. Atleast on a 350 cube motor. I wouldnt go bigger unless you needed more rpm. Tpi in the bolt on shelf parts form wont give you rpm, you would have to follow what the california guys are doing for tpi that can pull rpm and make power

 

And what are the Cali guys doing ??

 

Using aftermarket tpi bases but cut and welded for larger cross section at the head port side. Injector bosses are raised up to allow for a taller port to better fit the 190-210cc head ports which are commonly 1205-1206 gasket sized. This allows for much greater flow and thus can get the most out of the heads. They are making 360-400+ hp at the tires and smog legal. Its pretty incredible

Typical base with mild porting without welding up material on the base will flow 250-260 cfm and kinda limit you to mid 300's whp. Doesnt really get all you can out of a good 190-200cc port head. Welded up base may see 300 cfm and support well over 400 whp.

All depends what you want to do. Good set of heads and intake base with mild cam will give you mild manners but build big hp.

 

I might have one those manifolds available soon.
I just need to get it checked out.

 

Also, that head looks like a tall port if it fits a Vortec pattern.
Might as well buy a pair of AFR 195 #1040's and be done with it.
You would save a lot of money.

 

I think he has been bitten by the cheap parts prices.
I'm not trying to be mean at all. We have all been there but sometimes its better to spend a little more up front than trying to part it all together.

 

You should go shopping for some good used parts here for cheap.
https://www.thirdgen.org/forums/engi...5cc-heads.html
Also check out the rest of the Parts For Sale page for great deals. I bought a TPIS ZZX Cam and Superior Axles from here.

 

With TTOP, No mention of where the heads came from we can only guess.

Id take a pair of new GM vortecs over the probably overseas piece at least you know what youre getting.

 

If you want a decent aluminum head you can get dart shp's and jegs brand/pro-filers for 900-1000 complete. Not a bad deal and make decent power. Shp maybe alittle behind the pro filers.

Used parts are a plus sometimes. Generally need replace springs depending on mileage and cam you are using. My bud has some brodix race rites i think 200cc for about a grand. Light use. Look around you can find some

 

If you are looking to go cheap, you might consider doing what I did. Picked up some used 113s and ported them, then they were sent to a machine shop to be cut for larger valves and get reassembled with new valves, guides, springes, and retainers. I also used a ported Corvette TPI base because the 113 heads need an external egr provision.

 

world product sportsman II, 200cc runner, 64cc chamber and 2.02/1.6 valves, theyre iron but for the price i like them

 

Had my eye on a set of those as well.
