Using a piston with a -5cc relief and stock head gasket, you're around 10.8:1. Stepping up to the Impala head gasket (.029") will result in 11.5:1.
But keep in mind that SCR is just an arbitrary number - you should be more interested in your DCR.

they were right at 800.00 for the pistons and 125.00 for the wrist pins. so 925.00 basicly. my engine builder buys je direct. so i'll try and get a series name, ie; 23* extreme duty flat top, etc...
