Pulled the head, and the gasket failed in the same spot, top of the cylinder on the intake side of #3 and 4.
When I went to zero my nip gauge, I realized it was not totally flat, so no nip #'s yet.
Disassembly torque on the head nuts seemed low, at about 50ft/lbs to release the nut, but I have no frame of reference on how much they relax with heat cycles and gasket compression, let alone the thread lubrication situation. It went together with at least 90 ft/lbs and ARP lubricant. Hate to think I need to re-torque the nuts after break-in...
CC'd the head (37cc) and piston recess (27cc) @ TDC and with gasket volume I think that gives me a 8.39:1 static compression ratio.
