Comp cams

I've used 2 sets of Comp flat tappet lifters in the last few years. Both sets were old stock, one hydraulic and one solid. Both engines worked out fine and both still running. I might still have the boxes, didn't know there was a date code on them. Both were broken in on break-in oil, can't remember which brands I used, and soft springs. Hydraulic went to Rotella 15w-40 and the flat tappet is on 20w-50 VR-1.
