Matt good to hear you want to do your own version, just remember there is way more involved to make a front plate than meets the eye. You might be better off doing your own version based on the GA16DE Nissan head which Feral Erol had matched up to an A series sometime back.

A member went to 82mm sleeves A15 offseting 2 and 3 bores towards each other and this made the A series head a problem to use but no probs for the GA16de head it was intended for.

I would suggest you use the GA16DE head which are Nissan and use the Z5 pulleys which are tiny in diameter and would look very smart. The GA16DE head has the issue of chains but Im sure you can work out a plate so you can use pulleys instead much like the Mini head that uses the chain driven BMW head

That way the stock waterpump could be used like here on the Mini A series below
