What is the preferred brand of roller rockers out there on the market now? Used with a hydraulic flat tappet. I suspect faulty bearings in one of mine and will confirm that hopefully this weekend. Thanks in advance.
HS seems to be the preferred/popular one as there seems to be issues with others. Most recently I've seen issues posted about Scorpion but the vast majority of problems seem to be centered around PRW and other Chinese knockoffs. I have a set of PRW's on a HR 455 and its only just broken in so I plan to replace them with HS rockers soon.
Bowties are for Pee-wee Herman. "Chevy": even the name sounds cheap, but not as cheap as your Pontiac will be with an LS transplant.
What were the scorpion issues? I've run 3 sets for a few years with no issues. I know someone posted about the blue coming off where the pushrod contacts, but that was a few years back and i noticed that they have a steel black insert pressed in there now.
I have a set of 1.52 comp roller tips/adj. 7/16 bolts that came with some other parts All the roller tips roll freely and not sloppy . These look diff from another set I have and I wondered if older ones were diff from newer ? These have been soaking in a atf and wd 40 mix for a few months and still have a black look to them . I thought it could have a coating on them . Not sure but just a diff appearance
