Killed another cam, need to go roller, need recommendations

I run a lot of Clay Smith Camshafts and lifters (Buena Park CA.)
Their products are not E bay type cheap but neither is losing
an engine.

They race NHRA National Race winning stuff from
Stock Eliminator to Top Fuel (Langdon family are the owners).
I have never had one of their cams go flat or have any lifter
issue in over 60 years. However, I do know something about
what I am doing with this stuff after 70 years at the track.

I have to bush the lifter bores in the Stock/SS racing we do.
If for no other reason than the geometry angle on Mopar blocks
varies all over the place. At a 500HP level I believe imprecise Camshaft
operation can cost you 10 to 20 HP on some blocks with significant variance.
By the time you spend the effort to set up and check the block = You may as well
correct and bush the darn thing.
