I just finished my first valve job this week. Runs better (obviously) after 64K miles. I had to drop the engine because somehow the two M6 bolts next to the frame got buggered and would not come off and I had to grind off the heads with a Dremel. Was not a difficult task and I highly recommend that if you reach the point that you need this performed. You do it. Total cost $250.00. Gasket, springs, new head bolts, two replacement M6 bolts, spring compression tool.
