Bob and folks,
I concur with the concept that there are multiple head for the federal cars. I
had not grasped the concept that the casting marks (including cast numbers)
would be foundry dependant. I have tried to create the cross reference chart
using the casting number, stamped number, and TRF catalogue number (thus year
and configuration) and came back very confused. The same casting number would
have various stamped numbers and vis-a-verca. I did receive input from Ashley
Southgate (thanks Ashley) about NZ cars and it only muddied the waters. Sounds
like I need to get the ol' calipers out and measure specifics on each stamped
number and look for correlation's. I'll let the list know what I find.

Hi,
I'm not an expert on TR6 heads, by any stretch - witness my earlier postings.
However...
Jody - I think you may be wrong on this. I have seen several later style
heads with circle B desiganation. The circle B is a foundry designation.
And so would the block N designation.
There are at least four style heads for US Federal TR6's, probably more.
There are actually only two styles, but there were multiple foundries. So
at a min. there were early, early circle B, later, and later circle B.
There are also TR5 heads (these fit the the later style intake manifold, I
think). And there are a couple of other heads listed in the Roadster
Factory TR6 Parts Catalogue, Vol. 1 (hmmm... second mention today) - those
being PI and PI Police version, if memory serves.
I've never tried to cross reference the head numbers, but all triumph parts
seem to have the part number cast into them somewhere - it might be easy to
get the numbers from the head and see which ones match the TR6 Parts book.
The problem with TR6 heads is that there are several numbers cast in, and
I've never tried to make a match of the casting numbers to the part numbers.
Oh well.
See ya,
rml
