You might want to go through the pre-load check on the ball studs on that side of the engine to see if the adjuster on the valve that caused the problem is out of spec. You might be able to head off future problems.
If you were able to get all that for a case of Bier, then for another you should be able to take the little measuring tool and a valve spring compressor home for the weekend.
E-mail me if you want a soft copy of the procedure.
