Meticulous Mouse For The Mule
The Chapman 15-degree, CNC-ported aluminum cylinder heads from Scoggin-Dickey are almost too nice to bolt on, but that's where they do their magic. I know the small-diameter, stemmed Ferrea titanium valves are a little overkill, but I like quick revving engines--and lightweight gear helps the engine "yacha, yacha" when you snap the throttle. The head gasket is a .041-inch Fel-Pro composite with a combustion fire ring (everyone calls them the "blue" gasket because they're blue, imagine that...).
