Fresh heads last about 150K miles before they wear the guides. New seals can buy a little more time but the guide wear is inevitable.

Yea, I'm used to other brands where the entire engine is starting to wear out at that point and just a valve grind leads to problems.

It also makes a difference what climate the car is used in. Sub zero temps and hills are way harder on a car than sunny sky's and level ground.
