Default Timing chain noise? Ls1

Stil have som ticking rattle sound in my engine. 2002 c5 corvette Ls1
Want to TRY and get it to sound smooth
Was wondering if the timing chain is making some rattle ticking noise.
Anyone have some experience wit the timing chain goin bad and making noise
Have changed the Lifters (Ls7 Lifters)
Rockers look good (Little play and no damage i can see)
Balancer look good (no wobbling)
Air con tensioner is making some noise, so going to change that.

Thanks

Timing chains are not really known for making noise. In an LS1, there's no damper or guide for them to rub against.

And all LS1s tick to some degree, at least every one I've ever heard. Some louder than others.

Aside from changing parts, what have you done to isolate the problem? Used a mechanics stethoscope? Evaluation from a trusted shop?

Yep. Many things can cause a ticking noise such as a bad lifter or misaligned spark plug.

Just changed the lifters
Rockers look good
no exhaust leak
plugs are tight
Removed the belts and tensioners
Ballanser looks good

Stil have a ratteling tikking noise....Worst at 1000- 1200 rpm

The only thing left in my head that can make the noise and is rotating is Pistons and crank.. and timing chain and oil pump
