> [@81Boo](#): > > what ratio 1.5 or 1.6? roller tip stud mount right? if you are gonna use the cam from me with stock vortec heads, then you must use 1.5 rockers for 3/8 studs lift would be .477/.480. if you get modded vortecs, then you could do the 1.6 rockers which would make the cam liftright around .507/.510 ---

> [@81Boo](#): > > no, the ones that came on the engine you could use 1.6 on them, but why did you change your mind on the vortecs? those heads need freshened up, valve seals were leaking. you said you were using vortecs and didn’t need heads, so those were freebies cause i didn’t feel like taking them offf. ---

roller cams are better in general cause for one, they make better power and they last longer as rollers have less wear on the cam. they can have big lift and smaller durations. or you can have both big duration and big lift… or even big duration and smaller lift lobes. the ramp rates on those lobes can be very steep and make better power over regular hydraulic lifters. you can custom grind these cams to fit any motor need. all depends on your setup what you want to run. ---
