I decided to rig up a degree wheel to use in setting up the valve train. It's just a paper 360 degree disk stuck on my trigger wheel with a pointer off 1 of the studs for the cooling shroud. It should be interesting to see where valves open and close.

The adjusters are swivel feet. The one in the picture is an old pointy thing I ground so I could see better. Here's a better picture of the adjusters. Note they are not on center engine front to engine back. A couple are about 3/4 of a mm one way or the other.
Reading the cam at the valve just drove me crazy. I had to keep asking myself how many times did that go around. It turns out the cam has more lift on the intake than the exhaust but a longer duration on the exhaust. The intake ramps up faster so the duration at .050" is almost the same. The rocker shims are thicker on the 1, 2 side than the 3, 4 side. I think I have it right. Dave Attached image(s)
