Solid Lifters need help!!

I don't believe it's a good idea ever to run used lifters, except on the cam they came off of, and only then, on the specific lobes they were run on.

During break-in, and later too, Lifters and camshafts create a mutual "wear lpattern" on the face of the lifter and on the lobe of the cam that is a compatable configuration. Once the cam is broken in to that lifter, and that pattern established, they are then, a "Pair" or a "Matched set" and cannot be separated.

You can usually get away with running a brand new set of lifters on a used cam, but to just take a set of used lifters and put them on some other "used" cam is a no-no.

If you have a used cam, you need to hunt down the lifters that were used on it, and be sure the right lifter goes back on the lobe it was run on; all lobes will have a different wear pattern, and this is critical.

You can probably get away with running a brand new set of lifters on a used cam, but even that is "iffy." By breaking it in with weak springs, and using lots of ZDDP, you probably will be okay with this, but not with a set of lifters that were run on a different cam on your used camshaft.

Good luck with this, and don't spare the ZDDP, in any case...

That's just my 2-cents. Your mileage may vary...
