What's my CR?
wow. you might have wanted to figure that out before you ordered the parts. 
only GUESSING, you will probably be somewhere around 12.5:1 depending on gasket thickness. my 408 with 62cc heads is 12.9:1.

I trust him WAYYYYYYYYYYYYYYYYYY more than I trust myself...I highly doubt my motor will have a 12.9:1 CR... that's NUTS!
I am thinking more along the lines of 11:1

Well the stock LS2 heads are a 64cc so going to a 62cc shouldn't push the compression up to 12.9
The 11.1:1 would probably be closer to the truth as long as the head gaskets are the stock thickness (thiner gasket would raise the compression as well).
