Cylinder Heads 101

Hey BJR, again excellent post. I have had better results with the .528 over the .484 cams. The .528 has 60 degrees of overlap and the .484 has 68 degrees. I always have better vacuum with the solid .528 than the .484 hyd cam. Everthing else being equal. My compression is on the low side @ 9.02 to 1. That .484 cam is too soft on the bottom. JMHO. Anyway ..keep up the great posts. Terry.
