Rebuild time for the Nailhead

I ran another compression check and then a leak down test on each cylinder. There was quite a bit of leak down, some cylinders were at 50% at the bottom of the stroke and over 30% at top dead center on the compression stroke. All of the leak down was past the rings, valves looked OK so time to pull the motor and take it to the local machine shop that has done Nailheads before so off to Morrison Auto Machine in Glendale AZ for a refresh.
