I'm in Fayetteville NC and I have a couple noisy high energy lifters and it's causing some odd valvetrain problems. I'd like to swap them out for stock to see if it fixes my problem. I have a couple stock sets, but they're at home with the rest of my engine parts and I'm stationed at bragg. I'm just looking for a decent used set that someone has lying around that have good rollers and aren't collapsed, have 400k miles, etc. Please email me with what you got, my tapping noise is driving me crazy! dhirocz@yahoo.com
