5.9L Magnum questions

I'm thinking this grind from Oregon- 213/220 @ .050”, 265/275 adv, .480”/.498” lift, 110 sep, becàuse it looks a lot like this original 340 grind - 0.430in/0.444ex, Dur 268in/276ex.
Any reason this wouldn't work well as a 360 roller?
that would be my choice for the set up/parts that you have to compliment it.

with a 3.55 if you put wings on it that early a would fly.

put whatever exhaust you have on it while you save for headers. no sense in making a half step with whatever combo of manifolds for minimal gains.
