Westcoast, the scrws are burried in the head, you can't get a dremel in without slicing the head some in the process.

Gene, try shortening the short arm on your allen wrench as short as you can get it and still clear the rocker cover mount. Use a box end wrench on the allen as close as you can get it to the head and the while you have a good deal of pressure, whack the allen / box with a small hammer. The shock may break it loose for you. Of course, you need at least three hands for this, or the engine mounted solid so it isn't going to move.

Sears/OSH/maybe Kmart as they all sell craftsman now, has a set of scrw removers that are 1/4" drive and look like a counter sink with reverse cutting edges. You may try one of these and see if you can get it to bite. You may also want to try using a power screwdriver set to a mid torque rating and use it like a mini impact wrench. Increase torque until it goes.

One last thing, is the 1/4 drive allens you get in the set. Your bolts are probably metric, so take the inch alen that is slightly bigger and carefully grind the face of hte bit to fit the metric screw. OR use the one that is just to small and cut some shim stock to get it to fit. Then put the breaker bar on the sucker.
