Basically i'm interested in finding out whether there are similarities, given i've done a quick search and could find little on the topic.

 

Could a twin manifold from a datsun 1200, fit a 3/4k head??

 

As a seller on Ebay mentions that his twin weber manifold does fit a 3/4k.

 

Regards.

no, the heads are nothing like each other

i seriously looked into this as i wanted to put a 4ke system on my a14

well, the datto manifold set is about 2" longer, so your k exhausts would be in the outer intakes of the datto
