That squish band is nothing to worry about. What do you think your head gasket does?
If you are worried, go to a large animal vet and get some 60 mL syringes and cc the head and piston (at BDC and then subtract off the stroke X area. Figure out your CR.
I did this on my 911 and shimmed my heads to give a 9.8:1 CR with 9.5:1 pistons. 9.8 is supposedly the max you can go without twin plugging.
This looks likea great build.
