920 heads - What Cam?

Hello,
I was starting to replace a leaky timing cover gasket and realized that I'm half way to a cam swap. I was looking for cam suggestions, but haven't really found any good threads on my setup. if you could be so kind.

I've got a 73 duster
1967 318 out of a charger, this means it came with the unusual 920 heads (one or 2 years only on the La318?) and is supposed to have higher compression.

I'm wondering what cam suggestions people have. I just drive it around when the weather is good and to go mountain biking. I would like a little bit of a lope to the exhaust note. Also, I've done one cam swap years ago so I don't really remember it. do you think its worth the extra effort? Thank you
