I'm fairly new to the ls1 game, love the power of this car but may consider a head swap and a new intake to crank out a few more HP. now if i went with a different set of heads, would my valve train still work with the new ones? I've heard of 243 heads, but have no idea what LS engine they come off of. do they bolt right up? how much gain would I expect, will all my valvetrain bolt up?

what would you guys recommend?

243's (ls6 heads) are a direct swap, worth 15-20 hp over stock. Id recommend advanced induction ported 243s, worth 40-50 hp

are you talking about the 226cc heads or the 218cc ones listed on their site?
