Valve Train Noise
Has anyone had any success dampening some of the sewing machine noise you get with a cam and head package. Maybe some dampening material on top of the valve covers? I love the added power but the valve train noise is getting out dated very quickly.

The only problem with that is how would you mount the coil brackets?
Check out your headers by the head. They let a lot of noise out too. Mine sound like somebody is tapping them lightly with a hammer. I wonder if wrapping them would help.

I've got the sewing machine sound at certain rpm's in certain gears. I've never heard it standing outside of my car though. Only inside at low rpm's. Its really not that obnoxious for me though.

Do you mind me asking how much were they including installation? I have the 921 dual spring setup.
