I made a system to move the spark plug in a casr iron 8ba head. Unfortunately it's rather complicated, and not a consumer product. At present I'm not sure it will work. However, if it does you could do this to a pair of EAB heads, angle mill them .070" and have a combustion chamber around 60cc alot cheaper that any aftermarket head. At 87 I work in my shop trying to profect the perfect flathead. Maybe non of this will work, but it's agood reason to get up in the morning. Before they throe dirt on ya.
