Default clicking sound

i wonder if anyone out there can give me some advice on the clicking & knocking from my engine when i go full throttle. at first i thought it might be bad gas or the timing was off but now i am wondering if it could be my pistons or valves?? any suggestions would be appreciated.

Mine does the same thing, and the ticking is directly related to engine RPM. The previous owner said it was the exhaust manifold gasket... :crazy:

I did that screwdriver trick on the injectors when it was idling and it's the same exact noise. If you hear actual knocking, then it might be something else, but it could just be your injectors.
