Four Thought
|
This is the first of the four-port intake, four-port exhaust heads. The head was originally made in about 1934 by the Morales brothers for use at Legion Ascot. It was a single overhead cam in its original form, not a rocker arm. In later years, Joe Gemsa got the pattern from Morales and renamed it the Gemsa head. He converted it to a rocker arm operation, although he did build a few overhead cam versions too. This was a nicely designed head and ran very well. View Related Article
