Should i even bother with with getting a higher compression ratio?

I kind of have the same plan. Is it necessary to upgrade springs with a mild cam upgrade? Rookie questions but what would be the maximum cam lift?? using stock springs in a 5.9 magnum?

Around 500 is the max. Stock springs are really soft. Like soft enough to be able to compress with your hand.

The hughes kit (which I have on my motor) gets you more clearance and stiffer springs that are well suited to a mild to moderate cam.
