I wonder if the track will be worth a shit this year???
All the Branch heads I've seen have very polished ports, razor thin seats, surface ground rocker and head gasket surfaces (to get them perfectly parallel) and these numbers stamped near the intake ports (on the bottom).
....otherwise they look stock from the outside.
The early 900 Sportster Branch heads are not as common as the 1000cc heads.
I took my friend Chad's rebuilt '65 panhead engine to him the other night . . . and the first thing you see when you pull up - is the lamp in the window. Kinda hard to miss it...
