Yes, that's a big issue that has to be addressed when running higher psi.

What's an efficient way to address it? and at what power do the heads lift?

increasing head stud size? etc?

Thanks.

new to the ls, and doing the same build with the same goals. i was thinking callies comp rods with a forged piston and hellfires rings. stock l92 heads with spring and valve upgrades with a custom cam. tc-78 with snow meth and large front mount. would the crank really need replace (complete callies $2,100) or rods and pistons a good go for a few seasons? plus im having a hard time with ecu and wiring to mate with a good trans. this is a good thread, i very interested in hearing from the gurus.
