Has anyone done a 493 using these pistons and edelbrock heads? I have a fresh pump gas motor and looking at my options for swapping the pistons out and getting rid of the hydraulic roller in it. The pistons in it are diamond 52415 flat tops with -12.5cc. Currently at 10.4 to 1 and these bring me to 13 to 1. Race only motor no street time

If you the block or heads have not been milled it should work fine. If they have been milled a Cometic in the thickness needed to maintain piston to head clearance might be in order.
