I have heard about the 113 L98 vette heads, and that they are a good choice because they have the same compression ratio. But what other options do we have? Thanks

 

There's the TrickFlow Super 23 cylinder heads, those are the ones I'm looking at getting for my LO3.

Those heads have a 56cc chamber so your compression ratio will go up. As far as I know the stock heads have a 58cc chamber.

 

Sounds a little too expensive for what im wanting to put on a 305. Anything else?

 

port the hell out of ure heads ive been told several times u can get some pretty respectable numbers out of those heads when ported.

 

Why you want aluminum?

The only budget oriented options would be 113 heads, the L98 heads, vortec heads, maybe patriot heads, or get 081 [305TPI] heads, or port what ya got. Everything else will be $$$. Vortec you need to get a different intake manifold to run though.

 

it's been suggested to me to get aluminum because they are cheaper to port plus the weight saving. I also want to go get a cam that would push the limits of my stocker heads, i don't want to ride on the limit when i can have something that can take more then what i want to throw at it..

 

If you want cheap and aluminum, go with the 113s. I got mine with LT4 springs/lifters and a mild port and polish for 600$. But most of them ive seen are the bare heads for around 500$, so for all the stuff their missing and even a mild port job, they can get very expensive, very fast.

Basically unless you find a good deal, aluminum wont be cheap.

What cam are you going with? Whats your target whp?

 

Ive got a set of aluminum 128 vette heads the only difference from 113 is they use the old style manifold but are still a center bolt head i got mine with a 5 angle valve job port polish also ti-retainers they were milled to 53cc they cost me 800

 

ellaborating on this are the only options for a smog legal cylinder head the edelbrocks?

 

question, how much weight would one save on aluminum vs steel 305 heads.

 

You save about 15lbs per head.

 

Heard its a little more then that. I think its more around 40 or 50lbs per set vs iron.

 

I see Summit now offers their brand aluminum. Not sure of the cc size. you may need to shave them. Another expense however.
