wiseco pistons and ls1 heads?
hey, Ive been in the process over the last few months of getting parts together for my turbo 5.3. Wiseco recently came out with stock bore flat top pistons and according to their site with a 6.125 rod compression ratio is 10.4 with a 61cc chamber. If I were to bolt on a set of ls1 heads, would that be an acceptable way of getting the CR back down for turbo use or should I still consider spending a grand on custom slugs? I dont have any numbers on head gasket thickness cause thats still in the air as far as what Im gonna use but I think the stock MLS gasket is probably gonna be it. I guess on alot of numbers and came up with a CR of 9.3. If anyone can figure out the CR a little more exact than I can Id appreciate it or if anyone has any thoughts on going this route itd help me out a ton cause I know I can just trade my heads for some ls1 heads and be on my way, they get higher compression I get lower compression, win win.

243 castings (64cc) and flat top pistons will net 9.9:1 , why not look at a set of 317's?

yea 317s have a 72? cc chamber..

241 (ls1 heads) are not going to breath as well as the 243 (ls6/ls2) but the 317's will drop compression and breath as well as the 243's.
