[Healeys] 100M Head

[Michael MacLean]

 OK, I'm getting an education here too.  So, what is the number stamped into the top flange of the head in the picture?  Also Kees mention I have the wrong washer under the head nut.  Someone needs to tell Moss then, that's the one they sold me for that purpose.Mike MacLean

 Thanks for the info, and I did know that, but just talking about parts that the average restorer/judge can see.

The 100M camshafts were also numbered, Either 1B2892 or 1B2895.

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

 When I bought this head from my restorer friend that has passed, he told me it was off a 100M.  A valve stem had bent on startup and the valve, valve guide and the hole for the valve guide were damaged.  When I was putting seals on the valves I noticed one of the valve guides was larger in diameter than the rest.  This was the repaired valve and guide.  Luckily it is an exhaust valve so a seal of the type i am using did not need to be fit over it.  My question is, a lot of the body parts were stamped with the chassis number on a 100M.  Did they also number engine parts?  This head had been cracked in the past and repaired correctly.  See the " X" welded into the top of the head in the picture. Mike MacLean
