Any new progress on this?

Hope you don't plan to continue messing with LH...
Wow, beautiful workmanship! Very nice.
Have you thought about adding a MegaSquirt just for logging? I think you could tee off existing or temporary sensors and get temp/map/maf/rpm and afr (with wideband) but not timing advance. Once it's tuned and happy, you could sell the MS for not much loss.
Waiting for the head work to be completed. Intake valves recessed another .010", exhaust valves recessed .040". Based on the calculations, that, along with the increase in piston volume above the ring land & larger flycuts should get me down from 10.7:1 to 10.3:1.
Try using this calculator: http://www.race-cars.net/calculators/compression_calculator.html
It's pretty easy and accounts for all the bigger items - you'll need to subtract your .65mm piston popup from the gasket thickness and enter it in the gasket thickness box. For the ring land clearance, which I've never seen before, you can put your calculated volume in the piston dome box (-.925cc). I'm not sure why the valve flycut gets added in at all - isn't it already accounted for in the measured chamber volume?
[BTW: the value of pi in the equations you got from the other site is off a bit; should be 3.14159.]
