another thing to consider is that static compression isn't that important, go online and find a decent dynamic compression calculator and go from there, that will factor in the cam, cam timing, and valve overlap events.. previous guys have hit it right on the head, hell a prius is like 11-1 if u go by traditional standards, but its a modified atkinson cycle so its dynamic compression is pry closer to 7-1 or something crazy low like that.... Good luck, and hope u figure out a happy medium!
