Jesels are really good, but the most expensive and you have to set up for individaul shafts - which is a huge expense. If I were looking for a top quality set on a big cam motor again I would go with Harland Sharps. Smaller cam street motors can get by with something like Hughes, or Indy or ..... Many experts (I am no expert) believe that you are better off with rockers that do not have fulcrum bearings for a moderate street cam and spring set up. If i were running a moderate roller cam with less than .550" lift and spring pressures below 180 / 550 I would probably try some bushed fulcrum Huges rockers or something similar that do not have fulcrum bearings.
