They quoted me $400+/-. I think and it was worth every penny! Took them 2-3 days when they snapped off one of the plugs and had to drill it out.

I have no doubt I could have done it but having read all the problems others had out there, I wasn't in the mood for a challenge.

Mine had maybe 175k miles with EGR in place so it was really sooted up.

It is not cost/time effective to DIY IMHO. Take it to a dealer and qualify for your next 2 years of roadside assistance to boot!
