Is it okay to re-use Roller lifters with 55K on them with new cam?

 

You'll be fine if they look good, assuming your not running killer spring pressure.

 

I'm running crane dual springs good to .600 lift and a 232/242 .533/.560 cam

 

I rebuilt my whole motor and stroked it and thats the one thing I didn't replace. The guy who did the machine work said I didn't need them. Considering I was getting all my parts through him (mostly), I would have to say he was honest. He said just like Nateh said......dont need new ones unless you have heavy spring pressure.

 

I think you'll be OK. Just look at the rollers for uneven wear, nicks, or any galling.
