All right, I've been letting it sit there for a couple of days, but no one
has picked it up yet, so I will....
So, Robert, are you telling the group that you need a head job??

There were a number of foundries that cast heads for Triumph. The
foundries all used a different casting mark (usually on the front of the
head on the manifold side but under the valve cover).
Circle B is a scrolly-looking B (like the B in Bentley) inside a circle.
There are others, Block N is one.
The Circle B heads were sought after by racers as the castings are
reportedly thicker than the others, hence they make a better candidate for
porting and milling (e.g. you can take more material away without
compromising the head.
