i not a big fan of roller tips all the friction is at the ball of the rocker and not much on the tip if you run a full roller rocker for 40.00 more .i have used crane builder . or blue racers .harland sharp.scorpions/howards cam.and other that are more money but if you go full roller i would not plan on seeing more then 10.000 miles on them you will need to pull off the valve covers and check them .i had harlands in my every day truck they had 30.000 on them they were getting abit loose
