TO FIND your STATIC COMPRESSION ratio!
true bore dia.
true deck to piston height at TDC
true stroke
true cylinder head combustion chamber size
valve notch volume
cylinder head gasket thickness
dome or recess volume on piston top surface

USE THIS IT WILL HELP

btw where it says (Enter a negative number for a domed piston. Regular number for a dished or dimpled piston. ) its wrong do the OPPOSITE, NEGATIVE FOR NOTCH.POSSITIVE FOR DOME
