With the cost of new pistons, why would you want to risk using old slugs?
I am sure you could get away with it if they were in great shape, but why take that risk? Murphy would more than likely get you sooner or later. (More like sooner in this case, me thinks) ~Michael

Most of what you see there are folks looking for idiots as customers or some very rare pistons that are nolonger manufactured and are desireable for a restoration rebuild.

If they are pistons for press fit pins I wouldn't even think about using them. Pistons with floating pins may be re-usable.

I have a set of used pistons in my hemi. Ernie Hashim bored my 331 to 354 and made one good set from two sets of used pistons. Taht was 15 years ago. You can find hemi pi$tons today but there weren't any available anywhere back then. Hemis are full floating w/ c-clips.

if new pistons are available for an engine it is unwise to use used pistons. pistons are very highly stressed parts, and subject to cracks, groove wear, and pin wear that the average person can't see or measure. most that we get in from customers aren't worth putting in an engine and we give strict warning on using them. pressing the pins out tends to crack the skirts up inside where the steel strut is on cast pistons this causes mysterious noises, before failing and taking out the bore. skirts can be collapsed, and strange pin noises are common.
