Cheers for the info mate

I just went off the rego papers which say 69 model but if the numbers tell you its a 68 then thats what it is

Not sure on the head, i know it has oval ports and double valve springs, i think it could be A14/15 as it has the water ports under the inlet ports for heated manifold and i had to use a A15 intake gasket when i put the webbers on...if that helps

Here is a shot of the spark plug side of the head, what can ya tell me
