DO NOT UNDER ANY CIRCUMSTANCE USE OLD LIFTERS WITH A NEW CAM ! ! !
Regrinding is not an option. Do you want to take a chance and ruin
the new
cam, plus have to go through all the work to replace it when you
trash it
buy using old lifters? Not worth taking a chance, and while lifters
might
appear flat they are in actually ground with a very slight (around
.002)
crown. Regrinding, even if you add the crown would remove the
hardening
causing rapid lifter/cam wear (and I doubt your friend reground it
with the
crown)! Unless you have the equipment to regrind and properly
harden
(doubtful) than don't even consider using old lifters! Don't just
take my
word for it - ask any competent cam grinder or engine builder -

Barry I am sorry for the ambiguity. I couldn't/wouldn't do this my
self. I was thinking about having a qualified machine shop do this for
me. I have been told many times "new cam new lifters", "same cam same
lifters same lob". I was wondering if it was possible to be reground by
a qualified shop?
