273 Cam Shaft Wear?

I investigated getting my 65 2-barrel 273 cam reground to the factory HP profile (4-barrel). One place could do it (Oregon Cam, I recall) since they had the blank, cost ~$80 + shipping both ways. I switched to a 4-barrel intake. I ended up installing a hydraulic cam and Rhoads lifters. I installed the common "RV torquer" which is slightly more lift than the 273 HP solid cam (0.422"/0.444" I recall).
