I recently aquired a Fox 35 Red Head.... I personally have never heard of them.. what is the Red Head designation? is it a speed or combat or stunt engine?

Yep It is a ROCKET, I have 2 new ones here in my FOX collection. It was a low price sport/ combat version from the Black head 35
FOX made a lot of 35s
from the FOX history web site
1958
In 1958 Duke Fox figured a way to get more power from the combat special. He improved the intake port timing, he improved the piston and baffle, and he painted the cylinder head black so that you could tell the difference from the first combat special since they both look the same except for the above mentioned changes. Also, in 1958 Fox introduced the new .29X Racing Engine. It looks just like the black head .35 except it has a new style cylinder head with machined fins and is aluminum color. This engine has only "Fox" and a circle on the bypass and has a bore of .738.
1959
In 1959 Duke Fox introduced a "low price series" of engines and called these engines "Rockets". The first model Fox .35 "Rocket" had a red head and the name "Rocket" and a rocket design on the bypass. The intake venturi was made smaller than the previous combat engines and it did not have a removable insert. Aside from these minor changes, it looks like the first and second Combat Specials.
