Cam for LA...

I’m with toolmanMike, also why would you want a flat tappet cam when you have a roller cam motor? Just buy a roller high-po cam? Way Less risk of a run flat cam
This risk factor is on the machining of the block, more specifically the lifter bores being straight and round. Not the cam and lifters. The internet craze of cams going flat isn’t what everyone thinks it is and is IMO blown out of proportion. In my 38 years of playing with engines and more camshafts changed out than most people would ever do, I have one and only one cam go south on me. That was my mistake. I rushed it. The lifter bore needed to be addressed.

If the flat tappet or camshaft doesn’t have a taper ground on it, there is the other failure point.

Otherwise, IMO, if the cam is new and cheap, it’s a possible route to take. The possible draw back is the parts cost needed to make it work. Does the cam come with lifters? How much are the oil through pushrods?

This is where adding everything up comes into play. With recent price increases everywhere, this should be checked.
