need help on a f1a setup!!!!

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?

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
