Title: A65 Cylinder head
Post by: Mike Farmer on 18 Mar, 2018, 16:50

:)Hi gents.

Remind me please---I believe that the only difference between the "early" head and the 1966/70??? head is the change to the drilling of the two rear head bolt holes. From 5/16th to 3/8th. Would one of you kind guys confirm this for me please. I cant find anything else except maybe the threads --CEI to BSF/BSW????????. I really cant remember(AGE AGEN)

Hi Julian.

Thanks for that. Yep I had actually forgotten they changed the valves at about the same time. Thanks more
