James - I'd fit it, looks super trick.

Also, Not sure if you bought the engine fully complete, but it was already fitted with a 4 x 4 inlet and also the inlet was also ported to match the head that Karl Norris did. All the inlet manifold is beautifully ported, it took me days to do. I also took it to my local technical college where they checked that all the ports were equal on an air flow bench. On the third attempt I got all four flowing perfectly even.
