What was the issue with your PRWs?

I had heard bad things about the PRW's so they weren't even on my list. I got my HS rockers today and the bonus was the poly locks were included.

I used PRW 1.52 stainless steel roller rockers for my build using KRE heads (D-port 85cc 290cfm CNC ported heads from SD Performance. Ten years, only 13,000 miles but several performance upgrades over the years with a total tear down (more upgrades) 5 years ago. The roller rockers were checked over closely and were in super shape so reused them. All good and a lot of street style pounding on the car. Guess I got lucky.

Reading a post hear about the lash not staying constant(Cliff R) so I started checking mine(Solid roller) and sure enough the lash was growing and the oil drain plug had a fuzzy paste on it.

Sure it could be something else and I haven’t put enough miles on the motor since the switch to know the problem is solved. But I wasn’t going to wait.

The cheaper rockers like the Speed Masters are noisy,I did not like them due to how noisy they are and would not recommend.
Scorpion hold up .

Apologies, meant to say Crower 1.65 CRO-73624-16. I'm currently running these and very happy with them. Also ran Harland Sharp's on the street for many years with no issues.
