These are noisy motors to start with, once you throw a bigger cam, hardened pushrods and headers the noise only gets worse.

As stated above, swapping out to aftermarket rocker arms will help too. i just put some yella terras in and noticed a decrease in noise. As if you have a cam in there already, wouldn't be a bad idea for insurance.

Valve train noise is common specially with larger cams! The valve springs are so aggressive that you are hearing the valves tapping the head!

Check for a header leak at the head.

Pushrod length possibly wrong
