Another approach would be to boost it (you will love the power) and rebuild it when you have to. It is a great motor to boost, do not be afraid.
The fuel system you suggest will handle all your requirements. If you do not exceed 400 hp or so, you should be safe enough. As safe as a 1000k engine can be.

My stock fuel system was inadequate at 5 psi boost. I upgraded to 42# injectors and a Walbro 255 as you are planning and raised the boost to 7 psi at the same time. I ran 5 psi for about 4 months before tuning and didn't blow it up (although I didn't push it too hard). The motor had 80k miles at the time also. Now it's at 90k and still going...
