i have a choice between 402 ls2, with 70cc l92 heads, with -14cc dish pistons

or 402 ls2 with, 65cc l92 decked heads, with -22 dish piston and a thinner head gasket.

both being 9.6:1 CR

this is for a 14psi F1A procharger.

i eventually want to run more boost and gain more power.

what will hold up to more power and boost wise and what will last longer?

sorry im new to the whole FI deal.

so your saying go with the second option?

The first option has a thicker deck since the heads have not been milled. when heads are milled it takes away material that strengthens the heads and help keep them sealed under boost. plus some heads will be slightly less efficient when they are milled alot.

First option

thicker deck should allow you to give it a bit more boost without pushing water. do your first option. Good luck
