Does anyone have access to the original dimensions of the finned cambridge head. I am wanting to see how far mine has been machined.
Also I have seen some images where the heads have the small water hole in the middle on the exhaust side and I have seen some without the hole. What is the effect of this?
For what it is worth: mine measures 2 inches plus about 90 thou thick.
The under side is smooth with no visible milling ridges.
Location: On a hill in Wiltshire
