My next set of lifter will be BAM DLC coated. The only reason I did not use them on the -1 or Victor engine projects was the .210 intake lifter offset vs. Isky's .180. I know, .030, big deal. That .210 offset lister seat is *really* close to the edge in a .904. That said the current 451 project is standard port with standard rocker arm offsets so that will not be a concern.

DLC coating is amazing stuff. I have DLC valve locks in a few applications and they are really easy to work with and still looking like new.
