The head came off relatively easily although there was a bit of corrosion around the studs which held it pretty tight. Its a bit odd though, it doesn't seem to match the rest of the engine. It has no green paint on it at all, it appears to have been painted in red oxide. It also shows some marks that appear to have been caused by abuse, and the valve stems look very worn. Examination of the casting numbers just furthers the mystery. No-one on any of the forums I've contacted can identify the head. The best guess is Morris Minor or Austin A30. It doesn't really matter, it looks exactly the same as an 850 head, so for the time being I'll do it up to go back on. I'm actually considering something a bit more special for the head down the track.

I was very careful removing the timing gears, I'm well aware that the sides of the cam timing wheel are brittle and can easily be broken if removed carelessly. Once I'd removed it I discovered that it had been damaged and repaired in the past. Oh well, I thought, and went to find another in my spares pile. While washing the spare one, the side cracked out of it too, it must have been damaged when it was removed many years ago (what was I saying about ham fisted amateurs?). Now I'll need to find a replacement, but the good ones with the rubber chain tensioner rings are no longer available.
