You are running a very fine line between a stock cleanup/rebuild, and F-it, 355ci H/C build. Don't try for both here.
I spun my SBE well past 6500 for a couple years and never had an oil pressure issue. One day I will pull it apart and check bearings for how bad they were.

It sure is a fine line!
I guess the last question is do I have the deck machined and if so, how much? I see it ranges between 0.022-0.027". Assuming the heads are flat, I figured I could have it decked to have a 0.015" piston-to-deck clearance and use Fel-Pro 4.125" Bore x 0.39" CT gaskets for a quench of 0.405". I've read between 0.30-0.50" would be ok. SCR would be 11.29:1 and a CC503-ish cam would yield a DCR of 8.82:1 and cylinder pressure of 180psi. Should be safe for 93 octane ? Am I doing any of this right?
