Please consider a roller cam. Today's oils do not support flat tappets due to lack of zinc. Or add a bottle of break in additive each oil change, or you may wipe a cam lobe. I haven't pulled apart a flat tapper cam motor that was not heavily worn in recent years. Where 20 years ago it was not a issue.

A cheap option maybe to use a 95+ Vortec 350 long block to get a good roller cam cheaply.
