Help an idiot pick a cam - 5.9 Magnum

Heyah, guys.

My winter project list includes new cam for the 5.9L "Magnum 300" and I could use some help in picking the right one. My goal is for a strong/broad power band as I'm building this car to be more well-rounded rather than a dedicated drag car.

I have a 2600 RPM stall, will have (soon) 4.10 final drive. I currently have a 650 carb, stock heads...

Complication: Probably within the not too distant future, I hope to swap on aluminum heads and I'm also eyeballing a manual transmission conversion some time down the road...can those be accommodated with a particular cam or should they be done first?

Any thoughts, suggestions, random (preferably non-personal) insults, or golf tips are welcome.
