Does anyone know the actual bore size on a 4.500" , .040" head gasket? The best I can find is cc volume and computing it backwards it comes out exactly 4.500" Seems that may be a little tight with production variances of castings. I figured I would look for a shelf gasket before ordering a custom size. I have an overbore on this block and really can't believe this is all they make as a stocking part. Thanks, Beep

Oops, gasket number cgt-c5464-040
