Thanks for all the advice guys. Have decided to swap to a solid roller cam. Looking at the Lunati 40200734 , and I'm thinking it's best to ditch the PRW needle junk. I knew the needle bearing style was sketchy and a bad idea from day one, but as I said in earlier post it's what we ended up with by accident unfortunately.
I'm not sure what's the best budget rocker brand/style out there but I'll have to do some digging.
On a totally different side note, I stopped by my original engine builders shop yesterday to tell him about what's up and here's what he had to say about my current set up/issues.
- "thoes 987 springs are more then enough for your cam.
-geomerty could be better but not awful.
-somthings definetly moving around in there.
-i think it's a valvetrain weight issue, needs titanium retainers, and let's check the weight of the valves.
- not sure what's causing the rocker shaft marking issues..."
Haha well, not sure if any of that makes sense..like I said I'm noob and learning as much as I can when it comes to valvetrain.
