I found a used set of 1.6/1.5 ratio ProForm roller rockers locally for $80 bucks. They looked almost new, with no visible wear. I installed them on my 350 and so far I really like them. Quieter operation at idle, the larger intake lift gave it a deeper idle, and they really seems to have made a difference in power.

Now, after researching them, I found that Pro Forms have a bad rep for breaking apart. Anyone have any experiance with them? The quality seemed top notch, nice heavy feel, all the rollers turned very smoothly, poly locks worked well, etc. They appear to be the EXACT same design as the Harland Sharp RR's. Anyone know if they're the same?

The last thing I want is catastrophic engine failure due to a poorly manufactured Roller Rocker!
