The center of the piston has nothing to do with checking deck or zero decking! Cutting the pistons is the only way you can ever get all 6 of them to have the same quench, just decking the block will not do this.
I understand that. I was talking about cutting material from the center of the piston to reduce CR, I wasn't talking about decking. So since they'll have to cut all the pistons anyway to set quench after the decking, then it shouldn't be hard to notch them to set the CR right?
