Hydraulic Flat Tappet Camshafts, LA blocks

If we have a machined LA block, core plugs and cam bearings installed, a pre-covid HFT camshaft, yet don't have lifters yet, should I give up on the hydraulic Flat Tappet setup, and go retro roller$$? Mechanical flat Tappet? or risk failure? Of course on a tight budget...What would you do?

-3600 pound car, 2.76 gears, manual transmission, 360, going for daily driver.

Allot of failures out there with the new parts and oils .
Another factor if going to the roller rockers is valve spring pressure. I can't help you with your decision.
