Proform Rollers

old thread.. but none-the-less good topic. personally, i do not trust any roller rocker other the Jessel, Harland Sharp, or RAS.
This is really a case of you get what you pay for. with cheaper chinese units like Proform, you really have to watch that the
rocker clears larger diameter valvesprings, and alot of time the roller is not centered over the valve (side to side). also, the
roller is sometimes so recessed into the arm that the side of the rocker, rather the the roller, makes contact with the
valve locks instead of the stem! they also have a tendency to fail w/o warning and tiny little pieces will be all over the engine.. not to
mention dropping the valve. same holds true for other manufactures.. but to a lesser extent. all in all if you can afford to
go with Jessel or Harland Sharp, go for it! best investment for a stable litewieght rocker. the AWESOME RAS rockers are no longer available.
