Roller or Flat Tappet? Mild 440 build prep

Is it plausible to break in the flat tappet cam with weaker springs since you will do the break in period at only 2000 rpm? That might put in a good starting position.

That’s in the event you decide to use a flat tappet cam. I believe I saw someone comment on this before.

I’ve been watching Salter Racing on YouTube. Unbelievable expertise. He mentioned using a dial indicator to compare before and after lift after start up to determine if a lobe(s) has begun to wear out. He also recommends using a micrometer to measure to lobes front and back after getting a new cam to make sure you have at least a .002 difference. A new cam could be ground faulty.
Just some intel…
