In the 70's and 80's V-8 flat tappet lifters were produced in the millions. The aftermarket doesn't even come close to using a million a year. So production of these parts are now back burner.

New/Old mfgs have gotten into the game but without the OEM's standing on their heads with PPM QC levels the stuff out their is just not what it use to be. Compound this with BBC lifter bore angles usally being out a few degrees and flat tappet profiles these days are like Russian Roulette.

Cam cores come from 3 major suppliers here in the states. I do know of a Turkish supplier and few in Asia that are trying to do business here. For the most part X, Y, and Z cams all come from 1 of the 3 suppliers.

Hyd roller is what I recommend. RM is great to deal with and will get you the best parts for what you want to do I am sure.
