383 Head Gasket Recomendations

Is that an HP block? My L2315 +.30 are 0 deck.

I think there is a variance on an uncut block . 005 -.010 in the holes I have measured. That's a few different blocks.
The only piston I have found that dropped in at zero deck is the Badger piston in the 70's early 80's
