Default Real Engine Spec's

Looking for help on where I can find the real (complete) specification for the 1968 L79. My goolge search turns up the usual stuff. I'm trying to figure out my DCR so as I get close to the rebuild I know which parts to look at. The following is the info I need to plug into a calculator.

Cyclinder Head Valume (cc)
Piston Head Volume (cc)
Gasket Thickness (in.)
Gasket Bore (in.)
Cylinder Bore Diameter (in.) (4")
Deck Clearance (in.)
Stroke (in.)(3.25")
Rod Length (in.)
Intake Closing Point (degrees)ABDC @ .050 lift plus 15 degrees.

Hopefully this makes sense to someone. I just copied the needed info from a calculator off the internet. Any input would be helpful.
My goal is to rebuild to stock spec's using a modern cam if necessary based on the DCR. I would perfer to keep the 11:1 CR and iron heads. None of my goal is carved in stone, I'd just perfer to keep it stock but will make changes if needed or go the crate route.
Thanks in advance.
