There are 6 different pistons (that I know of) used in the 4G64 and G4XX Hyundai engines (4 are in the 4G64). ALL of them are different dish and will net a different CR.
The 8V piston can NOT be calculated as a "0" because it is not even with the deck. That also doesn't account for the valve reliefs or anything. You need to measure them to get the correct number. Either pull your head off, or go to a yard and rip one off.
Head gasket height should be measured compressed. Approximations will only net approximated numbers.
Measuring the correct CC volume is also something you should measure yourself. Again, rip yours off, or go to a yard. The CC volume changed many times on the different engines.
I'm not trying to be an asshole (please don't read this that way), but you would be giving out all kinds of wrong info without using the correct specs that were actually measured correctly, and proven that you did it correctly.
