You might try a impact driver . You can buy them anywhere . Its a kit with 3 different bits eg, phillips head and normal type . You place the driver onto the stuck screw and hit it with a hammer , the twisting action will loosen the screw. Make sure the slot in the screw head is clean . A little heat will help loosen it as well.
I've had varying success with 216 rebuild kits .... some of them come with low quality bearings that virtually fall apart as you press them in. The older NOS kits tend to have good bearings but beware as the lube inside the old NOS bearing may have dried up and it wont last long in service. You normally have to reface the surface where the carbon seal runs as it is usually pitted .
hope that helps .
