would it be a good idea to replace my stock strings i probably will ne wya but i want an opinion form you guys plus I want a heavier gauge
Go for it. If you're going to be sticking with the heavier gauge, I'd get a setup after you put them on, too. Have the action and intonation adjusted, along with the truss rod, to your liking.

Be sure to rape the blue note (augmented 4th). Rape it hard and exploit it like the skank it is.

Choice of strings and gauges is pretty much a personal choice. If you don't like the sound or gauge, then for sure change them.
