Not quite. You'll want the volume of the heads for later. The critical volumes you'll need are the volumes of the cylinder with the piston at TDC and at BDC. [Volume of a cylinder= π r²h. vol=((½ of bore*½ of bore) *3.14159) *Distance from top of piston to top of block. CR=BDC volume/TDC volume. The heads don't figure in because they would cancel out in the reduction of the formula. Also, cc'ing a head is an inexact science. Take a head to three different shops and you're likely to get three different measurements. (3.14159=numerical value of π. ) Suggestion: Do measurements after block comes back from machine shop (with a finished bore). Even a bore hone may increase bore size. It goes without saying that boring the block out does.
Pretty much.
I don't think so unless you have good reason to suspect a mismatched set of pistons. Measure after block deck has been machined flat.
Assuming you are taking metal off the head and the block deck, keep track of how much is removed. You will either need to shorten the pushrods or shim the rocker arm shaft by a similar amount.
Also, while assembling the motor, keep track of bearing-to-cap clearances (both rod and main). (Too loose, have trouble with oil pressure; too tight, excessive oil heat, engine does not spin freely.) Don't assume it's like replacing a gasket. Also, keep track of the crankshaft end play. (Can affect ignition timing if excessive.)
