Yes, it can be a problem for you, earlier 24v are more supseptible,,,, Search engine is a good thing on this site.... do a search for KDP or Killer Dowl Pin. I think Mopar1973Man has a write up on it as well.

Think Geno's sells a kit.... but I wouldnt spend the money,,,, in reality,,, a dab of RTV over the hole will suffice, most folks remove the case bolt next to it and fabricate a small metal tab that when the bolt is re-installed will reach over and cover the dowl hole..... again,,,, do a search, and read the FAQ files.... Mopar1973Man if I am not mistaken has a write up with pics.

A bigger turbo like a 62/12 or 64/12 and some 100hp injectors would be nice....

400-450 HP is also another good rule of thumb

That's not good information. More than one 24 valve has lost the KDP. There has been a dealer repair order posted for an '02 that lost it with a considerable amount of damage. ALL 24 valves are susceptible, although less so than a 12 valve. Only way to know for sure is to pull the cover and check.

Killer dowl pin

If you get onto spiketv.com they just had a show on saturday about the KDP and the best, easiest, cheapest way to fix it. It was step by step too. It was on a 12-valve but pretty much the same.

i disagree. a very good friend of mine works for cummins in ridgway and he swears that a 24 valve has no pin

I can guarantee he is wrong. Just ask Dave (fishing2deep4u). He has posted a dealer repair bill for a KDP repair on his Dad's '02. I have met Dave and know it's true. This has happened to more than one also. The 24 valves do have the pin but most of them have a case cover that prevents it from backing out. Not all of them do. Tell your friend so he knows too. One of my Army buds is a big wig with Cummins back in Indiana and he tells me the same thing but I suspect that's just the factory story. My guess is the assembly line just kept using the 12 valve covers until they ran out of them. Some were probably mixed in with later ones and ended up with a mixed bag which is how a few got installed on some as late as '02's. Just my guess on that.
