OK question is to replace lifters due to my dumbass not paying attention.
I found I had two burnt valves so I pulled the heads off and had those redone, in the meantime I decided to switch to a 4 speed from a 3 speed, so as usual things snowball and I start saying well this might as well be upgraded or replaced. Aluminum radiator, Holley fuel injection, 4 speed, new water pump, drive shafts eventually re-gear axles, etc......

78 CJ5 with 304 bored 30 over
Motor had been pulled and intake and heads plus valley pan were all off the motor. I was cleaning out the cooling passages and rotated the motor on the stand a little far and 4 lifters fell to the ground. Of course they I had no idea which hole they came from. Engine was recently rebuilt and has less than 3,000 miles and maybe 6 wheeling trips at most. it has a mild RV cam in it. The lifters look to me like there is very little wear if any and cam looks the same, but I am no engine builder by any means. So do I buy 4 new lifters, buy all new lifters, or put the 4 back in and hope they don't do any damage to cam or lifters. I've read not to do this but I've asked a builder who say run them they will be fine. Just looking for the NC 4x4 insight an consensus.
Pro's, cons, or your experience experience No I'm not going to LS or 360 swap.
 
After learning a bit more about your situation I say buy them all and do the new cam break in procedure.
 
Is there a chance all new lifters could wipe the cam out?
