[6pack] Get into my Head

[Kevin McNelis]

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.
