Heads

[V895]

I am undesided on what heads to use on my 4.3T engine to get the most most bang for the buck with out having somthing that can't take driving down the road. I have a freash set of Vortec heads off a 95 Tonwanda 4.3 that I can build but don't know how much it will cost me in going this route. If I do use the heads I have now this is what I have in mind of doing to them:
Port/polish
Flowmatched
Stainless valves
Titainuim springs, keepers
ARP rocker studs

Or should I just go buy a set of Bodix heads and get it over with.


I plan on over-building the engine so if in the future if I deside to put more boost in it or and something else I don't have to tare the engine back down agin to have to up grade somthing in order to do so. This is my fist Turbo engine built so I will appoligize in advance for all the qestons and the ones the will probly come.

Re: Heads

One advantage of aluminum ,in addition to weight svaings, is that if you ever "hand grenade" your engine, you'll prolly be able to weld up and fix your heads. W/ cast iron, it can still be done but not nearly as easily.

Buddy-o-mine sank $1800 worth of P&P work into a set of iron heads only to have a couple of pistons smack the heads and cave them in on the first pass. :tdown:

Re: Heads

If your planning on using stock exhaust manifolds, the Brodix's are out (evven the straight plug are still slightly different plug angle than the stock plugs) If stock manifolds are what your planning on one of the Vortec options would be my recommendation.

Re: Heads

The vortec's will put you in the ten's maybe even lower, are a lot less hassel, are easier to work with and wil cost you less. Yea, I say go the vortec's!

Re: Heads

I will be using after market turbo manifolds would like to make a true twin turbo set-up on this engine whether I have to build my own manifolds or not.

and just my :2cents:, if the heads are 1995, then they are not vortechs, they are L35s, but those too will get you into the 10's.
