Roof made a 16valve C head yours will be third model

I heard about the leaks through the pushrods. The guides on top of my head look different from others I've seen. 4124 sounds about right for the BB head serial number. I'd be curious to what other A head serial numbers are. They said rajo made over 4,000 heads.

The B head came out in 1918. I found a number 270 stamped above the water outlet could this be the serial number, anyone else have a number there.

Is the master carb rare? What year did they make this model?

Does anyone know what year this model head was first starting to be produced? How many did they make?

Thanks Mark. I would be interested in buying an ori intake manifold if anyone has one.

It has eight plugs 18mm you just can't see them in the photo, B's had 1/2 pipe thread. Does yours have the slanted casting by the fire wall.

What year did rajo stop making heads?

I believe this is the BB head. It has eight 18mm plugs no 1/2 threads and a slanted casting by the firewall. The serial number is in the 12000 range.
