Head Gasket ( can't find stat, standard gasket kit from Full Throttle, can't find listing)
Factory crank and rods.

nowhere enough informatin to say what your static compression is. You need to know piston dish cc's, head cc's and head gasket cc's (and of course stroke length is factor as well)

Help much appreciated.

I have all required info for calculating the CR, except victor reinz #3797 head gasket specs....I've googled it to death with zero luck.
Looking for Head Gasket Bore Diameter, and compressed thickness of the #3797.
