I ran these for the last 20 years
Measured about .015 in the hole , give or take , on my 71 383 Magnum
Was closer to 9-1 Compression with Fel Pro .038 head gaskets
Was running the 284-484 cam and a set of machined 906 heads with factory size valves
Worked out awesome until I installed a pair of Eddy 75 cc E Street Heads with the larger valves of course and the same Fel Pro Perma Torque .038 head gaskets and tapped #4 piston with an exhaust valve within the first 200 miles wiping out a cam lobe and bent push rod
So my point is without valve reliefs in those pistons your limited on cam selection
Would have never thought a 284-484 cam would have kissed a piston when changing to aluminum heads and everything else the same
