too high compression?

130psi x3 and 135psi. well balanced....No head gasket issue or valve issue as I can tell. The EGR does move right off throttle so im wondering if I have it too 'loose'? Engine has new std. rings and pistons but cylinders were not bored: no taper on old cylinders, just a dingle ball glaze break.
8.6:1 is stock, under what my psi to ratio calculation is x(14.696)/1=130psi is closer to 8.8:1 (at sea level) does this sound right? And would a .2 point increase do anything in regards to knocking?
