Will the lsa heads fit on a sbe 6.0 or do I need to bore it and get new pistons? Any idea what the compression ratio would be with a lq4 or lq9 and the las heads? I already have the heads, just need to pick up a block. Thanks

the heads will fit with the stock valve size, they are just stroger ls3 heads with upgraded parts. minimum 4" bore however you will shroud the valves and they wont flow as much as they can on a 4.065 bore. always check valve to piston and valve to block clearance. are you looking for an iron or aluminum block?

iron. its gonna be supercharged, so not overly concerned about the valve shrouding. I only plan to get a year or so out of it before I build the bottom end
