Hmmm, doesn't sound good Mark.
first off, the allen screw is usually way down when it gets tight, atleast mine were.
Second, did you build the original engine? or did you buy it all done? The reason I ask is if you have a solid lifter cam, doing the hydralic adjustment method will leave all of them way too tight, and not let the valves close all the way, making it run like crap and almost impossible to re-start after you shut it off.
Any chance you have a couple of wires crossed? Done it many times myself.
