And Jim, you said this isn't a max performance build, but 15:1 and .800 lift cam sounds really close to max NA build..lol looking forward to reading about your build.
I figure since I am running alcohol, I might as well build a CR between 14.5 and 15.0
And B1 heads using 1.7 rockers ends up with 0.800" lift easy, IMO 0.850" would be more typical, especially for large CID engines (572-604 etc).
A more serious build should have a two four tunnel ram on it to feed the 572 CID.
Then a dry sump oiling system, vacuum pump, etc...
This isn't a street engine.... LOL
I will take a few more measurements to estimate what gasket thickness is likely to be needed. I do have a regular 0.035" and a SuperPerformance 0.047" on hand already.
