I have an LS2 in my 2005 GTO, and I have been considering purchasing a set of L92 heads for it. I was wondering if I will be able to use the set of stock length hardened pushrods that I already have, or will I need a special length for the intake? What abot valve springs? I have CC 918's in the engine already. Are they good with the L92 set up?

Thanks,

Tony

 

The answer to both question is: The cam will dictate what springs and pushrods you should use.

 

I will be using my stock LS2 cam.

The stock cam won't work very well with the L92 heads. You may actually loose power...

 

I also am running an GT67 STS turbo, intercooler, and meth injection

 

Then the answer is definitely - maybe. I'd still measure the PR's on install.
