Ive personally had atleast 3 engines various miles etc have the same things happen.

Only time I have seen the seats just drop out of the head is when they have been improperly modified or overheated. 260-280* is all it takes.I don 't understand what anyone elses experiences with a valve seat will have to do with yours since you no longer have a stock motor. The fact that you changed heads pretty much nulls out anything that might happen on a stock motor.

Email mailed tuned by Brent@dtpracing.comComp268cam,
06 300C 80K+ on the odometer and happened at startup.
this mainly happens on quick stops...when you get gas or run into a store then come to restart the engine...it has only been an issue on 5.7 mds motors with stock heads...I had a few theories on why thi happens...Just look at it like playing russian rullet every time you start your engine on a pit stop...
Quite a few have told me stock seats have .002 to .003 press on the valve seats. Talked to a few that this has happened too, only seen one set in person. In the past year, I have had to replace 2 seats on brand new heads that I just didn't feel comfortable with.
The Bear is coming.
06 Stock Magnum R/T with 117K on the OD. Failed on start after 5 min of being off, speeding ticket.
