Reusing lifters

I would re use them if they look good and have a convex face with no abnormal wear or scratches.
This of course is taking for granted that the cam is also good and you do not have heavy duty valve springs in the heads.
If you are ever in doubt, replace them to be on the safe side.
I have run used lifters on a used cam mix and match several times in the past with no issues.
Take everyone's advice on here and draw your own conclusions from all of it as a whole.......
