I just replaced the head gasket on mine. Since the head was off I had a valve job done. I was very critical when adjusting the valves to be sure that were set just right since the seat are fresh. Will probably need to do another adjustment in 500-600 miles after the valve break in more. But WOW she's a smooth running engine now. Won't be breaking any mounts any time soon.

Something else I found along the way of trying to reduce engine shake. The link that is running from the IP to the shutoff lever was just a fraction too tight. This caused my engine to be slightly shutting down when my foot was not on the accelerator which cause some pretty bad idle shakes(as if you where to just barely push on the shutoff lever but not all the way). I only found the problem because I had forgotten to reattach that link after doing some service. I had already started the engine and was very pleased with how smooth it was idling. I noticed the link and snapped it in place while it was running. Once attached, the engine suddenly started shuttering a little. I was disappointing that my service efforts where not the reason for the improvement, but I was very happy that I found that little easy adjustment. Sometimes bone-headedness leads me down the right path
