Very interesting, I have the books by Allan Scott the Kiwi involved with the engine development. I wonder if they have the bladder in the fuel tank that was inflated to get the correct amount of fuel for scrutinnering and deflated for the raceing 
And they are going to have fun splitting open the exhaust manifolds to bridge the internals to simulate/create headers?
