How much power does milling heads on 5.3 add?

I would talk to whoever is gonna deck the heads and see what you can do to get compression to as close as possible to 11:1 and run premium gas. Just a reminder.....stock CR of the LS3 is 10.7:1.
As mentioned, you may only get about a 10 HP rise.....but so what? It's torque that you're after.....and a 15-20 TQ increase below 4000 RPMs (less increase above 4K RPMs) would be worth the effort.

I may end up changing cams, but this is a budget build. I'm building a new crawler, it I have left over funds i may look into changing cams. But the ls2 came with new springs and spring tool for $75. I was really wanting to just delete the dod and pick up a few hp while I was at it.

All these fellas chiming in know their ****
Nobody’s trying to steer you off into “no expenses sparred” territory
Milling your heads thirty thousandths and the Cam Motion Cam will be worth 35 horsepower and 45 TQ over just tossing in that LS2 Cam
And you probably don’t even need better springs than the ones you have

Yeah, 0.525" lift doesn't require aftermarket springs. The LS2 springs would work well.
What's important about the suggestions you're getting is that they're based on the purpose of your build. If you were just building a cheap, streetable car, the LS2 cam would be fine. But specifically for a rock crawler you'd be better off with a different cam.

The SDPC Truck Torque cam provides big torque and power gains for 5.3L LS truck engines. Requires the use of the LS6 spring upgrade from Scoggin Dickey and Chevrolet Performance - Part # 12499224. A simple install for 5.3 owners for increased performance, power, and torque. This cam uses a 3-Bolt timing gear.Dur. @ 0.050”Lift (1.7 Rocker)LSAIntakeExhaustIntakeExhaust2052100.550”0.525”115

Almost the same.
LS2-------------- 204/211, .525/.525, 116 LSA
The cam above- 205/210, .550/.525, 115 LSA.
A little more intake lift, a degree less LSA, durations within a degree. It might make a little more power due to the slight additional intake lift and tighter LSA.

But it's a little bigger than the 2 cams above. What are you really after? You keep comparing VERY similar cams.

I wanted a btr stage 2 truck cam ,Specs are 213/218 .551/.551 113+2 but was recommend cam motion drop in cam. I can get this cam for 120 shipped. I'm on a strict budget. Is there gonna be a lot of difference in this and the brt stage 2 cam?

There's not enough difference to be really concerned about. If you can a buy cam even close to all the ones discussed for $120 go for it. The engine will run well with it!
