Mopar R3 Block

ok. so if it's the 59 degree 9.6 deck block that I want. What does a guy do for cam bearing or does a guy have a cam made for the bigger holes?
If it has the wrong cam tunnel, I dont know, that's probably what makes it "cheap" we have a FABO member @Rocket that knows more than I do about the difference, hopefully he will chime in
