Alright, so i'm looking for some heads for my new project. I'm taking a low miles lt1 I have and replacing the motor in my 96 ss with it. I'm going to put some really good heads on it and a pretty nasty, yet streetable, cam in it to use with the mods already on my car. I'm looking to make about 420-450rwhp with the setup. In addition to the mods already on my car i'm going to use a fully ported intake, bigger throttle body, an electric water pump and finish removing the egr stuff.

My question is which of these heads do you think would be a better choice for the build? http://www.advancedinduction.com/AiProductsLTx.html

Also any other oppinions are appreciated so say what you think.

If you call AI, they will also tell you what they think you should use.

 

for 450rwhp your going to most likely need TFS castings if your not going to run a SR cam. 420rw is a different story, stock casting (200cc) and a big HR cam should do it considering your an m6 car. The 30rw hp difference is really a lot. are you planning on a 383/396?

 

I think 200cc heads with a hig HR cam should work well for you. If setup right you should see 420-440. If you have the budget step up to a solid roller setup.

Ron is a great guy on the phone and very helpful. Call them up and ask for their oppinion.

 

Call them and get real answers.

 

thanks for the input, the reason i put 420-450rwhp is because if i make at least 420-430 i'll be happy.
