Slant six builders...Lets talk Cams

Well though I have been working on cars for a living since the late 80s most of what I have been doing is stock replacement stuff. I've rebuilt a few slants over the years, but again, stock /but machined to clean up and bring clearances back to where they should be. Done a little performance work on small blocks but even, then mostly stock.
Looking at cam charts, overlap, duration, etc makes my head spin. So on that part of this build I am leaning on others, who know and between here and the /6.org forum, the consensus is about the same for picking a cam, and what hardware to use with it.
Not trying to argue at all, RRR, but to be honest I have had more say that 318 springs are basically "std issue" replacement for /6springs, you're the 1st that I've had say different. IDK how much lift it takes to coil bind 318 springs on a /6 but this cam that I am wanting to run is right around .435 -. 440" lift. This is for a truck that will be used like one, I doubt it'll ever see 4000 rpm.
While I'm here, what would you run then, I wanna do this exactly once.

I got the closed chamber slant six head back today from having it machined for the 318 valves. It's going to set up about 1.840" spring height. I'm going to just run the Comp 911 single spring. They set up at 122@ 1.9, so seat pressure at 1.840 will probably be "around" 150 which is perfect for what I have planned.
