Branch Cylinder Heads

I've had numerous guys contact me lately about old ironhead cylinder heads they found...and they think they're old Branch heads...and they're not. 

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.
