7.3's are noisey stock and with Cold Air and Exhaust mods they don't get any quieter as you probably know from your mods list, but it's a different sound from the sound of Rocks in a Tin Can. Wife can always tell when I pull in the drive way. Let us know if you go the Line X route.

Well Im reversing my noisy mods like my stack and put a full 5" system with a high quality resonated muffler and I'm going to do the door seal mod with the tubing and re insulate the firewall I guess and the doors too as much as I can not looking for coffin 6' under the ground quiet but deffinately want to block out some engine and road noise. I just have gotten past the point of trying to impress ppl with the sound of my truck and doing what is good for my hearing lol please don't think I didn't enjoy ever second that I had that stack with a sh!t eating grin on my face but the full exhaust and muffler actually flows better than the stack made the truck quicker from a stop and 50X quieter I'm sure .

Id say give it a shot man.... maby try the spay can stuff first on a junk set of valve covers and see what happens. Put a few coats on to build it up.
The reason sound deadner is effective is that a piece of sheet metal actually transmits sound while it vibrates and pulses just like a speaker. In an extreme way it does the same thing as a glass of water on top of a speaker. So anything that will absorb those vibrations will be an effective sound deadner. Ive heard of people using line-x, rhino, speedliner, extreeme liner....... any polyurthane coating as a sound deadner with great results and great protection.
And the statement that line-x in thin is false, it can be sprayed as thick as you want. Its just the application that makes it thin. Can be sprayed 1/2 thick if u want. That stuff mixes in the nozzles when spayed and dries in 60 seconds after mixed. And can be sprayed over again.
