are harlands adjustable? Are harland sharp LS rockers adjustable? I had a motor built and just cranked it up so its the first time the lifters have had oil in em and I want to know if the rockers are adjustable or not to set the valve lash. Valvetrain isnt noisey but didnt know if maybe they were tight.
They make an adjustable rocker for Gen III heads but I don't believe they do on Gen IV heads.
Lifter preload is set by pushrod length with the non adjustables most people run. Just need a $20 PR checker to measure PR length and add in required lifter preload. Let me know if you need more info on how to measure and I can help out.
Who did your motor BTW. I used to live there and am familiar with a few of the shops that way....

Mayhem Motorsport did, not to pleased but its what I got. Prelode should have been checked as the valve angle was changed with my heads and a shorter pushrod was required. I just didnt know if the harlands were adjustable, never saw em b4 they went on
If they are quiet I think you are OK. I have never had any personal experince with them but they have been at a while so I gues they should be decent...
Having said that RPM in Garner would be my first choice in the Raleigh area. Those guys have helped me out a couple times and flat out know there ****. Just stop by there shop sometimes and check out what they are doing. Always 2-3 NASTY builds going on...

Yeah Ryan tuned my car too. I am getting ready to port my FAST and do a bigger MAF and lid and will be back up there for a tune tweak soon if nothing else pops up..
Not sure but I always thought somebody did RPM's shortbocks and they finished them off but I could very easily be wrong.
Any way tell Jason and Ryan up there SOMbitch said "hi" and good luck with your setup
