roller rockers and solid roller lifters
I bought the ohio crankshaft needle bearing/roller tip rockers and they rule!
I don't know about all the off brand rockers but you have to change the adjusters to harland sharps for the one tshat come on the off brand rockers are junk.fyi
Unless they are 12 points, there probably junk adjusters.
If you go with needle bearing on shaft rockers make sure you line the rocker bodies up with the springs so they don't hit, so shim them tight like .010-.015 side play.
You need induction hardened shaft too, call rocker specialties and talk to gary.
For rockers, adjusters and shafts was around $340 for everything when I bought mine.
They are only gonna work as good as they are set up.jmo
