I came across a pile of parts, a fully forged l92 with some worked heads in a pile of new boxes. It's all callies and wiseco rotating assembly. BUT the heads were originally bought for an ls2 so they were milled to keep compression right. Now, I found a l92 block studded etc and the bore x stroke comes out to a 418. What would be the effects of running a dished piston to keep compression right when the heads have been milled? Can I get away with it? Again, all parts are new minus block, which is a 2500 mile take out l92 with arp parts added. It's going in my 08 Sierra Denali.

You need to pour the heads and calculate your CR to know where you are now first.

double check ptv clearence and u could go with a thicker headgasket

To answer your question yes you can run a dished piston with no issue or degredation to performance. Most of the forged engines built are using dished pistons be it a -3cc or a -32cc.
As stated you need to know your heads chamber size though in order to get it right. You can use the hg thickeness to compensate a little as well.
You of course want to order correct for the head your using.

Cool. The numbers have already been crunched to maintain CR. I was just checking if I would lose much huevos over a taller chamber. Now the fun part, taking all the parts off the old and onto the forged! Thanks.
