la 360 timing cover or 360 stock magnum cover

Are you still wanting to use the factory magnum timing cover and serpentine belt setup?

If so, you can use the long snout cam, special cam bolt, and washer with the stock magnum timing cover, water pump, pullies, etc.

BUT, you will have to use an electric fuel pump. The magnum setup does not allow you to use a mechanical pump. I'm using a cheap summit racing fuel pump and regulator.
