Dads Toy

I just finish intalling the new head gasket. Man what a job that was. Work 15hours straight and did it all in one day. Turned over and startedt he first time. Only problem I had is getting the rocker arms adjusted right. Manual doesn't really right. I am trying to find the right way and the easy way to adjust the arms. Trying to do it the old school way of just running the engine and tighten the nuts until the noise stops, then add one 1/2 turn. Not sure how close I am getting.
