Should I wait until it learns Flare Blitz to evolve it or would

For in-game purposes evolve at 34 when it learns Flamethrower as Growlithe and Extremespeed as Arcanine after you use the Fire Stone on it
You can use a Heart Scale to teach it Flare Blitz once it reaches level 45 even as an Arcanine

You haven't actually tried that, have you? It doesn't work.

wait till 45 till it has flare blitz, then relearn extreme speed it would have at 34

That’s what I did.

Can't you just tutor flare blitz onto growlithe?
