Whats the difference?

Can somebody tell me the difference between the 16v head and the williams head?

Are there any issues about running the williams 2.0 bottom end with the 16v head?

You can run a 16v head with a willy head np. The difference, and I am sure I will corrected here, are mainly the size of the valve epoenings. The Willy has bigger exhaust valves.

what about head gasket are they the same? do the coolant passages match and stuff?

and if the bore size is slightly larger on the williams, it wont match the head of my valver. :?

iv heard the valve lift is slightly higher on the williams ws well
