I'm not sure about the compression off the top of my head maybe close to 12:1 but a 55cc might hurt the flow more than the compression will help. I'm not an expert at all but maybe someone can clarify.

i would be more worried about piston to valve clearance...

i am running .110 flycuts in my stock pistons with .090 clearance on the intake valve...

57.5cc and .040 gaskets...

i would mill less and run a thinner gasket...i see your quench being a hair high with that compression and might cause more knock than with the same compression and a tighter quench...
