Need opinions on rockers...steel vs. aluminum. Just a mild street motor. Hydraulic roller cam. Why one over the other? Thanks
What engine.... for the low spring pressure you would be normally running on a hyd roller either steel or alum will work fine... as to cheap rockers... well thats something that can bite you

I guess "cheap" is all relative here. I was going to use either the PRW's or Comp iron rollers. I like the lack of fatigue issue with steel over aluminum.
Even with a decent set of alum rockers you wouldnt have any issues.. your spring pressures will be pretty low

So should I consider PRW's cheap? You're right, with low spring pressure I don't need the best, but I don't want garbage either. I'm only looking at 375# open and 155# closed pressures.
I've never even looked at any PRW rockers to say one way or the other... so I'm the wrong person to ask that... I run T&D on all my junk... not cheap but very good quality but all my current stuff runs high spring pressures

I have run Hughes 1.6 aluminum rockers in that pressure range for 4 years now with no problems. I check them often no matter what.

Don't assume that any rocker is a bolt-on. Everything should be checked for geo and corrections made where indicated.
