? about DCR for my 350 sbc

I was pokeing around a few sites and read a little about DCR which im not fully sure about. I know my 350 sbc, has 9.0:1 SCR, but i dont know what the DCR is, which is what i want to learn more about. It is to my understanding that its suppose to be in the range of 7.5 to 8.5 for a street motor. I dont know what mine is, and would like to know if anyone could tell me. The motor is a 350 sbc, with stock crank and rods, plus KB120 .030 hiper flattop pistons= .007cc valve reliefs, that are .010 in the hole. The heads are WP S/R torquers = 75cc, beehive springs, 2.02-1.60 valves, and 170cc intake runners. The head gaskets are GM Performance .028 composset to give me a .038 quench. The cam is a retro-roller from Comp = EX270HR = 495in-502ex = 218in-224ex = 110 LSA. When i dialed the cam in, i used a 9 keyway timing set which was set on the (0) mark. If my motor is not in the 7.5 to 8.5 range, what could i do to change it. Please Advise
