[Healeys] 100M Head

[Curtis Arndt]

Mike,

No they did not number engine parts other than the engine number (easily
removable aluminum tag) on the block should match the chassis number.

Now the "M" distributors also had unique part numbers (there were two
types) and of course the H-6 carburetors were also numbered, either
AUC-6040 X or 6040 AA with of course the appropriate hand etched numbers
6047 and 6053 respectively.

Also on a somewhat related subject, a recent thread stated that
supposedly some "M" carburetors only had the number 6040 with no suffix.
However, I doubt that assertion as I have never seen any originals numbered
as such, and two other members of the Concours Committee (both 100M
experts) that I've spoken to say that they have never seen Factory "M"
carburetors with just a 6040 number.  I'm 65 and these two members are 15
years older than me, with a lot more experience.

Cheers,

Curt
