Need some help figuring CR

Assuming your measurements are good (no calculator is any good if the measurements are guesses and assumptions),wallace gave me 9.57 . Frankly i was surprised it was that high with the pistons that far down the hole..... then i remembered the steel shim hg, and the closed chamber head.
With a typical 906 head and a composition gasket, thats a high 7 to 1 engine.
