Thanks Chryco. that's what I thought. Unfortunately the idiot that last put this motor together did not install the correct length studs and even cut some of them off flush with the manifold. Looks like I'll have to remove the manifold to get the studs out. This all started because the ignition wire bracket on the left front corner of the manifold is attached with the throttle spring bracket screw instead of the manifold screw (which is actually, and incorrectly I believe) attached with a broken off stud...I can't get the air cleaner on if I leave it where it is so I figure it's in the wrong spot.
