IMHO leave heat out of it unless you are running a bead of weld on the race that when it cools will shrink the race, tricky to do when it is cocked. If you heat the head stock sufficiently to cause it to expand and release the race when it cools it will shrink ... not what you want.
I'm assuming the bike is on it's center stand with engine in. If so then you are loosing a lot of striking force from the head not being supported.
I would put a heavy support between the floor and head, think a 4 x4 post. I would use my air chisel with a long attachment that has a hammer head end to knock out the race but a good punch and heavy hammer will work. The support under the head is key.
