With a 0.025" piston deck height (piston down in the bore 0.025" with piston at TDC) 10.77:1 SCR with 0.066" squish/quench. Ideal squish/quench 0.035" to 0.045".
With zero deck (piston crown even with deck surface with piston at TDC) 11.51:1 SCR with 0.041" squish/quench.
What fuel are you planning to use?
Neither motor will run on pump gas without detonating and you'll need more cam, CL180275-10 for the 10.77:1 motor

and CL183365-10 for the 11.5:1 motor.
