Never did hear what those 'pyramids' were for...

Greg,
Look closely at the on stand shot. The valve covers are not bolted on. In the installed shot you will see the valve covers are on correctly. Mountain forward on passenger side with drivers side mountain to the fire wall.

I don't know the reason for the mountain on only one side. But, I did ask the late Mac McKellar why the oil sheilds, under the 1967 valve covers and newer engines and over the rockers arm that, where replaced by valve covers with drippers on them and no oil shields? Was there an oiling problem?

Mac's answer was that this was the inventor in him. It was a cost savings only. Never a oiling problem on top.
