360, You think it'll run on pump gas?!?!

Which pistons are you running? the 116 or 405? Pretty big difference in valve reliefs there...and that extra 5cc could make a noticeable difference in static CR. BTW, when I ran the numbers you supplied, and using 5cc valve relieves, 0.005" under the deck, with the .039x4.15" gasket, I came up with 10.5:1...either way, it is kinda high for static, and the smaller cam...but a modest timing curve, proper setup, correct stall and gearing to take advantage of the cam, and you should be OK, but using a thicker gasket would drop the same combo mentioned to about 10.1:1...hmmm.

Assuming the 405 model pistons with 10cc of valve reliefs would further drop it to 9.6:1...
