    If you wanted to do some custom headers you can get flanges for around 50-60$ this was the route I was going to go but the engine I bought came out of an obs project and came with a set of the schonfield headers already. Good luck with the swap that will be soooo sick!

    Damn, that looks a lot nicer than my CCLB.

    Did you ever find anything for headers?

    I just got done doing an intake gasket and the updated electronic injectors in my CC, and it made me realize LS motors are much easier to work on. I'm addicted and want to start motor swapping everything now.
