Those heads usually cc in at around 60 cc. I know someone who uses them for budget truck builds but gets them milled about .050 (around 56-58 cc's) along with .028 MP head gaskets for a bump in compression. He also bowl ports them and opens the intakes up to 340/360 gasket size. 1.88/1.60s are good, some of our people in the know here like a 1.94 intake in a 318 head. If your going to use a hydraulic roller but confined to a shelf grind, I like this one fairly well.

I imagine your better off with a custom hydraulic roller profile, because there are many hydraulic cams that have more lift area under the curve than most off the shelf hydraulic roller grinds. If going with a hydraulic flat tappet, I really like this grind for most street applications. I'll have to look at the cam card again but it's got a fair amount of advance ground into the intake it to help maintain cylinder pressure.
