2500 ROTORS STUCK 180,000 MILES 350 5.7

1998 GMC C2500

I am trying to change my front rotors and they dont want to budge. Do I just need more force and some heat, or is there a trick to it?

I think those are the slip-ons if I recall. If so heat may help, but I would take a big hammer and whack them from the center of the truck towards the outside of the truck. Spin a 1/3 of a revolution after a couple whacks.
