Heads, educate me please! I've been reading on the different kinds of heads that came factory on LS1 cars but still don't completely understand the differences. I know my car has the shitty 806 heads and the later models have the better 241's. My question is, does the standard corvette in 01 and 02 have the 241's as well as the ZO6 or are they a different casting number? Someone set my straight, I'm a little confused on what came on what. Thanks!

98's came with the worst flowing heads, which are the 806's. Then there are the better flowing heads that came on the later f-bodies, which i believe are the 241's. The z06 came with the 243 heads, which are the ls6 heads. I could be completely wrong but I am pretty sure thats how the heads go.

Thanks for the help, so with minor porting the 241's can make some decent power correct? I'm just trying to figure out a way to make good power while not putting too big of a dent in my wallet. Does the 241's have the same size valves as the 806's?

Well couldn't I also take a set of 241's and have them decked to raise my compression a half point or so? I've noticed people running the 5.3L heads but wouldn't they flow less? Or is the Runner size the same as LS1 heads? I'm definately learning something here! Thanks!
