Spare Motors...gotta have a couple.
I tried a pair of fabricated valve covers they had no gasket rail on the bottom and kept blowing the gasket out. I went back to the cast aluminum ones I have had for many years with no leaks. I " customized " them on a Bridgeport to remove the fins for a different look. The Magnum valve covers are still available as I bought a pair a few years ago for the 5.2 in my D150. I just got back from the machine shop myself checking on my spare 363 ( 360 Magnum block, 30 over / W2 heads ) I am having it redone from 11.5 to 1 compression to 9 1/2 to 1 compression for pump gas plus it had over 1,000 runs on it still ran good but was tired.
