143K. I just swapped a new head on, due to a valve seat loose enough to keep the valve from closing part of the time. Had a shiny mark around the edge of the valve relief in the piston, where the valve/seat was making slight contact, and the seat is visibly cracked at the point it is closest to the exhaust valve.
No, it didn't drop a seat, but it was about to do so.
I purchased a new head casting from J&C Enterprises, ( http://www.ebay.com/itm/350998600428...84.m1423.l2649 ) extremely pleased with it. Highly recommended.

I replaced the head with one from headsonly.com at about 110k miles as preventative maintance. It cost ~$1000 altogether since I replaced quite a few other things while I was at it, but well worth it in the end. I especially like the fact that I no longer worry about when the valve seat will drop!
It's been running for 15k miles or so now. :)

|Dmperfection||My '02 dropped #4 intake at 170k miles. Yes, I was a skeptic and believed that only those engines that weren't well taken care of were susceptible. I always ran clean synthetic oil, cooling system flush every year and kept up with t-stat replacements. I was wrong. Ironically, three months ago, I seriously considered pulling out the head in a preventative effort. I was skeptical and decided against it. One week ago, it happened to me. Now I'm tearing it apart.|
