Are aftermarket timing chains any better than the stock LS1? Im getting ready to install a cam, and figured that would be a good time as any to switch it out....if it is recommended.

Yes, because theres always a valve open and with the timing chain not there to make sure the valves open when they're supposed to, a piston can come to TDC while a valve is all the way open. This person this happened to had a motor set up for boost I believe so his valve reliefs were bigger than normal.
