What about Having them re-ground? Does that make them reusable cause it is a lot cheaper than buying new ones ,from my understanding.

Here’s the link to a past thread giving several other links regarding the subject of used lifters. http://forums.y-blocksforever.com/FindPost66378.aspx
. But in direct response to your question, reusing lifters that have already been run is not recommended for use on a new camshaft. There are lots of reasons for a new camshaft to fail and using previously run lifters on a new camshaft is just one of the reasons. The big risk is the lifters turning in the opposite direction in which they had been previously run. Assuming the tappets are used in the same locations, then if the lobe rake angles have been reversed from one camshaft to another, then lifter rotation also reverses. Any reduction in crown on the used lifters is also a deterrent for the new cam lobe break-in. Beyond all that, here’s the link to a list of contributing factors for cam and lifter failures.Cam and lifter failure causes

Is there a reason you need to replace the lifters if you replace the camshaft? If so what is the reason or can the used ones be reused.
