90 degree oil filter adapter or not?

I have a 360 that is going into a 1970 Duster with Hooker Competition headers. The Oil filter clears the header as shown in the picture. I plan to go with a shorter filter than the one in the picture. Do I by some other reason need to use a 90 degree oil filter adapter? I would rather not use it if possible. Anyone running this combo in a Duster? Thanks in advance.
