I'd really like to shoot for 9.5-10:1 static compression and .040" quench, for use of regular pump gas at 5500+ elevation.
At 5500ft, I seriously doubt that excess compression is gonna be your problem.
Scr is nothing but a tool to be used to achieve a certain pressure. A pressure known to to do what you want it to do.
Choose your cam first,calculate the Ica off the advertised duration, and plug your numbers into the Wallace calculator, and then work backwards. to your desired pressure/available fuel target.
For instance; your 360 at 5500, with a 340-type cam, will need 10.8 to achieve 155psi to run 87 with that .040 or less Q, in iron.. On 91 you can run it up to 11.0 or perhaps a lil higher.
Whereas, at 9.5 it will be a bit of a dog until around 3500 rpm.
With alloy heads, 180/185 is possible still on 87, and that might like an Scr of over 11.5
Now you got a ripper of an engine below 3500, but then you might run into a different problem, hi-speed detonation.
That 5500 ft is worth about a full Scr point over 1000ft. In other words a combo that runs nice at 9.8 at 1000, will need 10.8 at 5500.
