And I can identify folks that still have their stock EGR valve (and coolers) and can claim the same!
I'm NOT saying that the EGR valve doesn't contribute to coking. What I'm saying is that improper operation has more to do with coking than people are willing to admit.
I have cleaned enough EGR valves and intakes (cleaned out a head on one car) to last me a lifetime (two!). And on the cars that I did I don't expect to have to clean them again (and they STILL have their stock components). One car went 150k miles and was running perfectly fine: I cleaned things because I replaced a bad EGR valve (turned out the valve was fine, it was the seal that was bad).
I'm running the same setup as here:

"the intake was absolutely clean after 100k"
I guess the real question should be:
"How many clogged race pipes or SRP's are there with the same improper operation?"
If the answer is none, or hardly none. Then it is worth it. It is also worth not doing it if yours doesn't clog. Personally I'm really looking forward to it.
