Not bad. Just run some brake parts cleaner (or something similar) through it. Don't be too agressive with it or you can tear a hole in the diaphram inside. It's not a surefire method and you might still need to get a new valve when all is said and done, but it's always better to try cleaning it before you replace it

I have the exact same problem (code 33) on a 1989 F350 7.5L, but can't get the EGR valve off...should I really worry about it? I have a new EGR valve and would really like to swap them out, but don't have any ideas at this point (tried heat, PB Blaster, etc)

Not Really.
The problem on a bad EGR is usually packed layers of carbon that won't break down with brake parts cleaner that coat the valve and seat surfaces.
And it's very hard to scrape it out and still have a good functioning valve.
If it's a chunk of cinder causing the problem then you can sometimes get it out and have a well functioning valve.

So a stuck closed EGR would be EXACTLY the same as a normally operating EGR at high RPMs. Thats just the way the EGR works, no if's and's or but's about it.

EGR is closed at idle and closed at wide open throttle. Most of street driving falls into the EGR active range, and can cause pinging if suck closed, especially at higher loads, i.e. up hill at part throttle.
