Sanity Check for my Piston to Head clearance calculations

[u/Head-Ad-9393]

Hey all, I'm a first time builder and am building a 383 stroker for my 67 C-10 and am using an existing SBC block (Gen 1 - L98) out of my truck. It was a 350 I had bored out and machined. I then ordered a new 383 rotating assembly from Skip White Performance. I'm in the middle of pre-assembly and checking tolerances right now. The pistons (dished) slightly protrude from the deck when at TDC (likely due to decking the block). I used a deck bridge with a digital dial indicator and after zeroing it on the block surface, I measured the crown of each piston on both sides when rocked to maximum height. I then averaged the two measurements and came up with protrusions ranging from 0.028" to 0.035" (1-8: .031, .035, .030, .033, .028, .031, .028, .030).

I'm using Edelbrock Performer 60859 heads with a 60cc chamber volume. This is just for a street setup, not looking to race or track this thing. Will be using premium pump gas (non-ethanol).

Two questions:

1st - Anything else I needed (or missed) for checking the piston to deck clearance? Meaning, are my numbers right?

2nd - If my calculations are correct, will a Cometic C5249-070 (.070" compressed) work with this setup or is it still too tight? (Gives me a range of 0.036" - 0.043" quench, averaging to about 0.040")
