Like the title says, I keep wearing them out. I get maybe 4000 miles out of them. all on the street. Indy sr heads. solid roller .650" 272 276@.050. I use pac 1225 springs. these are also 1.6 rocker arms.

I do restrict the oil to the heads. I use a .040"
one on each head. Wondering if I should just remove them, and not use any at all.

The wear is not the shaft or the bearings. I think it is the aluminum bore of the rocker itself. They hold lash really well, but I can grab the rocker and twist it and get a lot of play. needles to say, they are loud and clacky. I use VR 1 20/50 for oil.

I just ordered a new set. Was thinking if a 1.5 might hold up a little better on the street. thoughts???
