has anyone built a motor for use with ls1/2 heads using aftermarket pistons and then swapped to l92s? were there any ptv issues? im doing a cheap 6.0 build and was wondering if they are interchangeable. i know the in valve is huge on the l92s and the valve placement is different. but i can get ls1 pistons for alot less cash than the ls3 stuff

You would have to bore the LS1 to 4" to use the L92 heads.

The 6.0 already has a 4.00 bore. If i were going to be using L92 heads in the future I would install the correct piston from the start.

My mistake, I know the 6.0 is 4.00 inches, I couldn't tell exactly what is was building, he mentions LS1 and LS2
