Cam selection for 5.9 mag

Only difference is duration?

You're going from a .42x to a .51x lift and that wont be noticeable?

I've got the one that ends up at .517 lift at 1.6 (but had to calculate it)

Not installed in anything yet but target is an LA roller 318 with 5.9 Magnum heads and a 999 trans with a small stall lockup.
