Explain to me again, please

We changed to solids in the LT1 car because the hydraulics we're getting tired. Went from 10-30 to 5-30 and had rockers coming loose. Car is no faster with solids... however..if we ever get it to the point we can win a heads up race. A zero weight will probably work a little better with solids.

Concerning cam and lifter wear issues with flat tappet cams, I was looking at my old Isky Cams catalog, and they offered some special "Hardface overlay" application on the lobes, which were meant to be used with their "Chilled Iron" flat tappet lifters. My catalog is from the 80s, so no idea if Isky still offers this stuff, but curious if anybody has any experience with these, in either a Stocker type engine, or anything else.

Rory,
Some NASCAR teams ran the Isky solids with the hard face overlay.

Also, although not mentioned often, Crower makes some great solid lifters with lots of options, including lightweight and billet steel lifters.
