Compression ratio estimates

Thanks Fishy! That helps. Now to figure out the best combo. Shave heads to 55cc....0 deck block...mill block to put pistons .03 in the hole...heads to 53...heads to 58... The options seem endless. Any suggestions folks. It seems that milling the block more and less on the heads may be better for intake fitment but I am sure there is some known happy medium. This stuff is pretty darn intriguing. This is my first motor build myself since all my other cars had somebody else make the motor decisions and I just chose what I wanted. thanks again.
