Some of you Triumphistas may find this interesting.

I have just purchased a NOS TKC 1155 cylinder head from my old acquaintance, Mick Dolphin. I want a spare as I am going to Stage 2 my existing head.
Still crated up, it is stamped TKC 1155 (but note it was something else earlier...) and further stamped SS27/73, which I know to mean 'Supplied Spare' and presumably dated week 27 in 1973.
As Home market Spitfire 1500's were still 2 years away, and only the US Federal engines were 1500 I reckon this is a left over Federal head, (possibly TKC1410 as it has valve inserts in both the inlets and exhausts) which was rebranded by Stanpart for the UK market. The head depth is 3.10" which also supports this view, So with a 50 thou skim I would have a NOS unleaded head, which will save a few bob! 😎
The accountants at Triumph were a canny lot!
