Try this, if the valve is open, turn engine on stand with valve pocket facing up, pour a small(capful) amount of your favorite flammamable product, I used denatured alcohol, then light it. Let it burn completely out then go in with your valve fork and try to move the guide. The direction you move it will depend on wether the "C" clip is still holding guide.
I'm tearing apart a 1940 block now and all the exhaust guides are stuck.
P.S. Do this in an open area, and keep a fire ext handy.
