I had my deck cut .025 to put put the trw/speedpro pistons at .000 deck height. The CH of the piston is advertised at 1.714. The calculations for an uncut block comes to 10.239.
My other block had 8 vr pistons with a 1.700 advertised ch were measured at .039 in the hole. Again the calculation puts the uncut deck height at 10.239.
I don't know if either block deck was previously skimmed to true them up. if so that would make the original deck height greater.
The .025 cut block is getting a makeover with a 4" stroke, stock length rods and off the shelf DSS pistons. The CH puts the deck height at .005 in the hole with the CR coming in a 9.9:1.
