I guess some of yall know what I'm talking about, my 5.3 has it and its about to drive me crazy! My wifes truck has it also but not as pronounced and her truck is bone stock, I guess my headers allow me to hear it more. Anyway a friend was telling me that if you swap em to ls7 lifters that this will quite em down. Has anyone heard of this? Or does anyone have any other suggestion? Thanks
LS7 lifters can be pretty damn noisey. The best ones for quiet are the Caddy race lifters.

Try some Lucas additive in the oil, usually quiets it down a bit.

You said you had headers, so Im wondering if it's possibly an exhaust leak? That can sound like noisy lifters too. Ticking like a noisy injector?
