la 360 timing cover or 360 stock magnum cover

So I am looking to purchase a cam for my 2001 magnum 360 that came out of a ram van. I am looking to keep the stock magnum belt setup and timing chain cover. I have heard that you have to use a long snout cam if you use the la 360 timing chain cover and water pump, correct? What advantages/disadvantages in performance can I expect using the stock magnum timing chain cover and a cam that is not a long snout application. Any wisdom would be appreciated.
