BTW .0062 off the deck = 1cc & for every .010 off the deck cut the intake surface of the head .0123
Therein lies a small problem and why I posted this.... Who knows if the heads have been shaved... they look like they have, but the intake surfaces look stock. If they were cut already the .0123 certainly hasn't been taken off. I just wonder if there is a way to determine what the factory height off some point on the head to the deck surface or something, so I have SOME kind of bearing...
