N/A(7A)- and T(3B/ABY)-heads have different cooling and cams. 
You should take a T-head, because of those and also the of the manifolds.
Still the compression will be too low. K 26 charger You have is maybe too 
slow for upgrading purposes? Even, if You´re gonna use Your K-jetronic, 
how about the ignition?

Of course almost everything´s possible, but this is a hard way.
Also picking up small parts and accessories, You need, is expensive.
I suggest You should get whole engine with ECU and all harnesses.
I myself tried to save and combine my 7A and a discarded 3B, 
some advices and calculations showed me to consider a complete
swap or nothing...Now workin´ on a different project :)


Good luck, what ever Your decide
