At one time I had searched all over Milodon's website for the reinforced timing cover for the big block Mopar's, they are not there and the one posted above for the 440 by SEbiscut isn't reinforced.
Andy's cover shown above is the best I've found. My other two choices would be,

http://store.440source.com/Fabricated-Aluminum-Timing-Cover/productinfo/200-1089/
AREngineering's cover and the 440 Source cover do not require water pump housing spacers.
The cam bolt thing is just something weird that happens with Comp Cams sometimes. I got one like that with the fine threads, every other 3-bolt cam has been 3/8-16.
