I installed a used RA IV cam using used HFT lifters in the fall of 2022 and everything worked no problem. I used 100# seat pressure CC cam lube on the cam and moly paste on the bottom of the lifters. Since the cam had not been run with the lifters before, I did a 20 min break-in cycling the rpms up and down. I used Crane Cams ZDDP additive and changed the oil and filter after the break-in, didn't find anything in the filter.
