Re: [Chrysler300] Manifold insulation for 300K

That packet is insulation to keep the valve noise down. There or not there, 
your option. Factory stock. Be sure to soak the valve stems in Marvel 
Mystery Oil or the witches brew of your choosing, then take a half inch socket 
extension and a hammer and bang on the rocker over the valve stem to make sure the 
valve moves. You can tell the stuck ones because they don't make a boing 
sound, rather a thunk sound. This until you have chemicalled them into 
submission. Just finished replacing a seriously bent push rod in the second 383 in a 
row that had sat for too many years. Always a good idea to remove the valve 
covers and perform the above soak, and hammer plan before starting the engine the 
first time. The previous B block spit out the valve lifter after bending the 
push rod. This kills all the oil pressure in the engine until you plug that 
hole up with the errant valve lifter. Current 383 retained the lifter but 8 
cylinders working is better than seven. Both push rods bent in exactly the 
same place. They are sort of the "Fuse" in the valve system.
