hughes cam quality?

I've heard of others having problems with wiping out lobes. Maybe due to improper break in procedures or wrong valve springs. I don't know. I've had one of the largest solid cams they make in my engine. It started in a 340 and is now in a 360. I use 1.6 rockers and a spring with a little more pressure over the nose than Dave recommended but it had to have it for the 340 to rev past 7500. Other than that I've had no problems with this cam even after 9 years and 2 different engines.

Oh and it was 3 tenths quicker than the MP .590 cam.
