I'm attempting my first partial engine disassembly and I have run into a stumbling block: Two of the screws in the front of the impeller housing are solidly frozen. Additionally, the slots of the heads are starting to strip out.
Removal attempts so far: 1. Soaked them overnight in WD-40. 2. Several raps with a hammer. (Normal hammer, struck the screwdriver handle, not the screw directly.) 3. Heated them with a propane torch (3 or 4 times, 30-60 seconds each). - I tried with and without squirts of water post-heating. - Before and after the heat, sprayed with PB Blaster. - Was the heat a bad idea, given the magnesium housing? The screws are still stubbornly in place. For what it's worth, the engine is horizontal, so the WD-40 and BP Blaster don't have the benefit of gravity to helping pull them into the threads. Help!!!

I've always had good luck, after the heat and penatrant, trying to tighten the fastener slightly. It seems to break the friction/crud holding the screw/bolt in place, and allows easier removal. Or it snaps off the head and you have a whole new adventure to deal with. (IMG:style_emoticons/default/smile.gif)
