I think a real good ballpark grind would be a bullet solid F/T with about 238/238 @.050 on 110 which I think is similar to the old racer brown Street Hemi grind.

The hemi rocker ratios are really low so you need a really sharp valve job to maximize the low mid lifts and keep the cam overlap down. get it right and a hemi can be pretty snappy.

Way back in the 80's there was a nice crower Monarch(?) cam that really woke up the hemis without killing any bottom end or drivability.
