B20 block and head choice for performance build 120-130

I had an immaculate, barely broken in early 70's vintage D cam that I got from a retired Volvo regional service rep. A "Cam Doctor" showed more nearly 10 degrees difference between the best and worst lobes as measured at .050 lifter rise. The person who did the test was shocked at the poor quality control on that cam. I read somewhere that the d cam is a duel pattern design, but these variations didn't correspond well with intake or exhaust lobes.
