Injector Cups and Preventative Maintenance
Hey all! I just picked up a 2003 Ex with the 7.3l, 275k miles. I need to replace the injector cups and will be putting in the stainless steel ones. My questions are:
1. Is there anything else I should replace while I have the valve covers off?
2. Are there any parts that I should replace for better reliability, performance, mileage while I'm working on it anyway?
3. Is there anything I should pay attention to with these beasts?
Thanks everyone!

You really want to go there? 
The sky is the limit, but with the valve covers off, injectors out, feel free to replace: Glow Plugs (OE) only, under valve cover harness, possible lifter springs, and shims, valve seals. I recently did that and more.
