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
it really doesnt matter...
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.
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.
