Finally getting access to mill for carving out my ohc 302 GMC head. Have decided to go with a single ohc because the sample I very crudely cut out of wood shows a crowded situation to use hydraulic dampened cam followers. The only out I can figure in using two cams is to run them right on top the valves using lash caps like the 4.2 jag engine. They are a pain and when we old truck nuts build stuff we tend to make it easy to work on and not have a bunch of sharp edges to get cut on. Why can't Detroit listen? This is like apples to oranges but here is a pic what just came out of the mill.
