340 street build help from experienced input

So, here is a question, so with a street car why a roller cam. Not a race car, so you don’t need to snap the valve open. Not chasing the last hp. Solid flat tappet. Much cheaper, dependable as a anvil. If the car progresses towards more power to take advantage of the heads. Then you can go serious solid roller. This has the feel of “it has a roller cam, whoo hoo” but not needing one, which is putting you in a hyd lifter box. I mean no disrespect.
