The heads on two of these screws stripped nicely last night trying to get the signal generator out of my motor so I can continue with the disassembly.

(parts 5&6)
I tried slotting them with a dremel and using a flat blade, but it stripped then too. Not much working room to hex-ify the damn things... Any ideas on getting them out without damaging (1) the sensor or more importantly (2) the engine case it's bolted onto?
I dripped some penetrating oil in there last night, didn't help. Can't torch 'em, aluminum case is behind them.
