Any thoughts on this engine issue

I gotta tell you demon, I'm not a pro engine builder, but I've built a few, and been into a few. Ya have me baffled. Next step, if you have not, is a compression check. I'd suspect something holding valves open, IE pushrods too long, sticking valves, broken springs,

Was this rotated with water in it?

I think I posted last night that we did a compression test and it was good on the gauge they all ready in the 150-155-160 range and held tight..... We also cranked the motor with the valve covers off to make even more sure the valve train was all moving... That checked out too....

Thats' when we stopped for the night puzzled as hell...
