put 243 heads on my 98ls1 need diff. bolts/gaskets?? I just pulled my motor out and im replacing the crank and bearings and all that. I already have a cam, and im thinking while i have the chance, i should upgrade the heads as well. I already ordered all the bolts and gaskets needed to put the engine back together. however, im thinking about getting a set of 243 heads, willl these heads just bolt right onto our motors? or do i have to get different head bolts or different gaskets or what? let me know!! thanks guys

This should be in the internal engine section. Anyways, I think you need different valve covers (center bolt instead of perimeter bolt). Using different gaskets for a tighter quench would be worth some hp. Also you might want to mill the heads to optimize the DCR for the cam.
