Just an update. Today after tweaking the timing I wanted to go for a drive, but the clouds opened up. So after the car cooled down completely I decided to take off the valve cover to see how the cam was doing. Well there were no discernible wear marks, so that is good. Eiji said I should check the valve lash after the first start up and 10 to 20 miles, and then again after it has about 1000 miles on it. Well I checked it stone cold and most of the valves were pretty lose. Which makes sense since I had a bit more valve noise than I was use to. Nothing really alarming, but more than my L24 had. So I set all of them to factory cold specs. Intake: 0.008" Exhaust: 0.010" I had two dedicated shims at those thicknesses, and two more no-go gages set at 0.009 for intake, and 0.011 for exhaust. I got all of them exactly spot on, which makes the OCD mechanic in me very happy. Some people hate even thinking of doing the valves. But I find it strangely therapeutic. Anyway, Still waiting to treat you guys to a video of the webers on the Datsun Spirit L28
