How much quench can I run?

Adam, yeah I think the dish will negate some of the quench effect too. However, eventhough the pistons are dished, they do have quench pads that line up with the deck area of the Eddy heads. Here is a bad pic of the piston dome...

Sorry it's still wrapped in plastic when I took that. But you can see the area above the valve reliefs and that small pad below the dish are at the compression height for the piston and they line up with the deck surface on the head. Hence my question, should I try to squeeze an extra .004" of quench out of it?
