You can do that if you want. Dishing pistons is more expensive that pulling the heads and opening up the cambers to increase their volume thereby lowering the compression ratio. If you dish the pistons, the e-heads will probably have to be cut to raise the compression back up where you want it. Aluminum heads will take about another 1 to 1.5 points more compression ratio to equal iron heads because of the better heat dissipation.

Your choice, Stewart
