Still no pictures, El Bandito, so maybe try to repost them. One other way to get a stubborn screw to move is to use a socket wrench with a small socket to fit a stubby driver bit in it and, if by chance you have the right size and shape of c-clamp, you can tighten up the clamp to hold the bit in the screw firmly while you back out the screw with the socket wrench.
You can try this and the other suggestions after your engine is warmed up. I like the heat.
hope you can get those screws out, good luck
