I am trying to keep my 68 as "stealth" as possible, am looking for "creative" ways to cut now on normal valve train noise...
any suggestions?

What noise are you trying to cut down on - solid lifters, something else?

If it's solids ( which I have but I like the sound ) you might try a composite valve cover instead of metal. Also, a hood insulation pad.

Stuff your valve covers with newspaper! I have really seen used car lots do this to sell a car! Supposedly, a thick aluminum valve cover like edelbrocks elite series cuts down on valve train noise. Or, use something like the coated 80's vette valve covers (center bolt).

This will not make the noise physically disappear, but rather allow your ear to accept the noise and realize what it is, and accept it.

OK: Go to the drags, (street or strip) and absorb an earfull of the other guys' motor noises. Listen to how much they brag, b1tch and hoot, and compare their B.S. to what you have under your hood. DON'T speak up! Just listen... After all your listening, go back to your own engine and listen to those lifters.... Nice ain't it?
