I am looking for others that have had a Valve seat drop on thier HEMI engine.
Please note here Model, Year, and Mileage.
Looking to see how many have been affected by this defect.

Ive personally had atleast 3 engines various miles etc have the same things happen.
BTW 6.1 motor for sale just so you know.
Licensed and Insured.
Modern Muscle 426 Built and ready to roll.
Tranmission valve body, torque converters. and blue top installs.
contact me for all your upgrading needs.
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.
