New Zealand Datsun Club

So i purchase an engine from a mate, it's an a12 with a14 head, ported, planed, kelford racing cam and valve springs..
BUT... it didnt come with all valve train, only the valves and springs.
So the question is will my existing a12 head gear work on the a14 head ??
(pushrods, rockers etc)

may pay to double check pushrod length but rockers are the same

A12 push rods will work with A12 Block, head will be fine. Is it Front Dizzy or Mid Dizzy, oil galleries to the Valve gear are different, this could be an issue.

I have a14 pushrods. 166mm. tip to tip. will these help. cheers.
