Chevy makes millions of roller lifters for their production engines- - - - -they're even hydraulic. Why not sleeve down the lifter bores in a stovebolt and have somebody grind a few different cam profiles for dyno testing? Even a reground stovebolt flat tappet cam would probably survive enough dyno time to get an idea what the grind needs to be, then contract for a small production run of dedicated roller cams.

Doesn't everybody have a flow bench and a dyno like mine?
