More work on heads valve seats made from drill rod along with tulip type valves. Valve seat angle of 45 degrees cut in lathe.Then after seat pressed in to head seat was cut with home made cutters with pilot shaft in guide to get concentric. Of course lapped in later and leak tested. Our family starting with my dad and now my brother have owned and operated an automotive machine shop for 63 years so I do things as we would on a full size engine.
It was at this point I started looking at the rocker arms and the very large hole for 1/4 32 spark plugs and started thinking this may not work. Things are getting tight.
More to come hope some folks find this of some interest.
