I had put some 2-3 hour trips on it to try to get time built up so I'd have a chance to inspect it before a much longer planned trip. The wear pattern looks good. I expected to see a little more oil when I took the covers off, because I had drilled out the oil delivery tube fitting orifice from .059" to . 063", but this didn't exactly flood the rocker area with oil...enough, but not to the point of robbing the rest of the engine of oil, to be sure. The valve clearance setting had to be adjusted, but I expected this due to a seating-in of the new bushings on the rocker shafts. I had swapped the shafts across the engine so I could start fresh on a new portion of the shaft. I'll check the clearances again in another 10-15 hours, just to be sure the clearances don't loosen again.

With luck, this'll hold up well.
