If someone were not to steadily beat on the motor, using it as a DD and only pushing it occasionally, would the stock RA with stock C/R be expected to hold boosted power ~ 8-9 PSI max (I.E. reaching 550-580 WHP on 93) for about the same life of the stock motor?
Fueling would also be upgraded to LT4 parts.
Average ambient temperatures and humidity levels similar to Florida.

For the Magnuson, you will be in the 550-600whp on 93 octane running 7psi and you wouldn't even need to upgrade anything else. If you wanted to be extra safe, you could run 530-540whp on 5psi.
If I were going to stay below 600whp now, I would run the Maggie, rotofab and add the JMS voltage booster for good measure. That also puts you in a good place if you should eventually want to push further. That's when you can upgrade the fuel system and add a cam.
