will installing a stock firmware on my phone make it SIM-locked?

I posted a thread somewhere else but I don't think it was the right place.

So basically my Samsung Galaxy S3 was SIM locked when I bought it. After getting it unlocked (long after warranty was void) I noticed the guys installed a really bad ROM and I want to reflash with a stock firmware. Will this lock my phone to a single network provider SIM card again?

Nope! flash away!
