If you are building an engine today (~2023), Professionals are not building Hydraulic FLat Tappet camshaft engines? Don't try?

Hay, don't bring me into this convoluted clusterfuckery. LOL
Knock yourself out. IMO, they are totally unnecessary on anything under 220 @ .050. I wouldn't use them anyway, becaus I am over and done ewith hydraulic lifters. I MIGHT would use the Rhoads VMax lifters, but most likely not, since the slant 6 is really not built for a hydraulic camshaft.
" because I am over and done with hydraulic lifters."

Why is that Rusty? -thanks for your information, time, effort, and experience!!

Because first, nobody makes a good hydraulic lifter anymore and secondly, solids make more power everywhere, so there's no sense whatsoever to go hydraulic. They were never made for performance anyway.
