Hi,
I read your post regarding the Spitfire head. What model Spitfire is it?
I used to dabble in Triumphs and have one or two heads laying around.
There's at least a Mk IV (1296 cc) and perhaps an older one (1147 cc).
(Maybe even a 1500cc.)
The only problem is that I won't be going there until Thanksgiving.
Let me know if you're interested.
Dave

I do alot of work with my friend Bim Shook, in Orange county Calif, on
vintage race preparation of Spitfiers.
He cuts out the entire section of the head where it gets thin when milled
to provide high compression. He then inserts a shaped piece of about 3/8 th
thick plate where the head surface is thinned, and welds in the thicker
part. He uses his 'bar B que' to provide the preheat.
We dont normally do work with the thoroughness of design you probably do,
but we can make some fairly good engines that stay together and will win
vintage races here in the So. Calif area.
If you want some pictures and TIG rod numbers, I can get you any
information you may want.
