Thanks to all for some encouragement and new insights..
My previous experiences a year ago on that engines tin screw, removal has been costly as in a couple feeble attempts, I had managed to drill off center (as mentioned by Don, Sarge and Jay that the screw doesnt snapp flat off), and also have broken 2 yes - (TWO ) easyouts. So I ended up taking that head to a machine shop a year ago just to fix my screw up.. When the weather breaks I will try all of the above suggestions guys, because there are probably enough broken screws in that engine.
