Surprisingly, no interference with crank so also a plus. Massive interference between the head and piston. Checked piston CH +1.280 so that is correct, and the rod length is 6.386 with calipers, supposed to be 6.395, so close enough. So winning some and loosing some. I did an extensive measurement of all the bores, and very impressed. My method is to set the gage @ 4.280, measure top, middle, and bottom, then the same but 90 degrees from the first. All bores min/max an incredible .0005 from nominal. That is good machine work and a great hone, (sunnen SV15).

The only reason I share this, is that, in my opinion, the cylinder hone is the most important machine in the shop as it finishes the bore id. If thinking of building a block, look for a machine like this in the shop.
Calculated static compression ratio, and it is right @ 10.75 which does not take in account the .004 clearance for the piston, X the depth to the top ring, which in my case is .300. FYI piston crown is approx., .230.
