Is it better to buy the heads and other needed things seperately or to buy them in a package. I have a guy selling me 6.0l heads for 350. Second question what else do I need to put these things on a stock bottom end ls1, I need the whole list, taking in mind that I have a supercharger on my car. I need help bad. hope you guys can help.

 

:edit: I screwed up sorry.

 

assuming the heads are complete all you'll need are the heads and some new gaskets.
