I want to thank everyone for information on milling down a Spitfire
head. I know that Ted is right - to be sure I need to cc the engine.
Anyway, right now I have decided to hold off. I have enough to do
without dealing with the Spitfire head.
The main thing making me think about it was I had the manifold off to
get it repaired - there was a hole in it about the size of my thumb.
Since I had the intake manifold off I was thinking it would not be much
more of a chore to take the head off as well. The welding shop got the
head done the same day I took it in, so for now I am not messing with
the head.
Thanks for all the information.
