Lightly used Cams
Lightly used Cams I have heard this and seen it in print but now that I am looking to pick up a set of 255's hopefully used I see everyone has their own idea on likely used. I know I may be opening a LARGE can of worms here but
using logic most 255's are taken out because after paying $35+ for a Screaming Eagle they want more bang for their buck the question is how many miles of trying to get something out of a Cam that that it can not do fits the title of lightly used.

I don't think you could put a number on maximum acceptable mileage since roller tappets wear cams very little in a normal context. Mine had around 5k on them, IIRC, and looked new--still going strong 28k miles later with the original lifters. I think most used cams you'll encounter on the market are CVO pulls and they likely will have low mileage. I wouldn't worry too much about it but would inspect the tappet and bearing surfaces for any imperfections other than fine scratches.

I picked up a used set of 255 cams that a guy used for "mock up" purposes only and only ran them on the dyno for several pulls, so he says......I would recommend replacing your stock lifters while doing the job that way all your components are new or almost new. I'm assuming your be using adjustable push rods? Look into the VThunder 850 lifters. Decent quality and price.

If you're buying a set of used 255 cams, make sure you're getting them as low-mile takeouts from the original CVO motor. You can find them on the used market for less than 150 bucks. If they've been installed in a second motor, as far as I'm concerned, they're worth maybe 50 bucks, max. That's because there's no reason to take a chance on a set of third or fourth-hand cams, when there are plenty of low-mile takeouts. Once they've been in a second motor, you don't have any way of knowing where they've been, or in how many motors, or how many miles they have on them.
