You can run Manley flat tops with the stock heads and be at 10.5:1 and mill the heads from there. That's what I did to get mine to 12:1.

No, because I removed a lot of material around the intake valves. You would need to CC the combustion chamber, then remove some material and then re check. You could get close by using a compression calculator on Wallace Racing.com and decreasing the head gasket thickness, but that won't be exact.

interesting post, did you have to notch the flat tops for the 3v?

Not sure what you mean...

No, the 3v's have clearance for days. Even with my milled heads and flat tops. Of course that is with everything running correctly. With my 560 lift cams it will hit if you rotate the crank with the timing chains off.
