273 Build

I'm just starting on a 273 build for a member here...
A couple of questions about your engine if you don't mind...
How much deck do you have ?
What was the bore diameter of your head gasket?
Do you have a final cr number?
I found the compression loss unacceptable using the 4.070 to 4.100 gaskets that are out there.Even at .030 that's 6 tenths of a point.
