Part of me is tempted to check the elongation using the dial indicator method described in the FSM and then replace the chain when I see some elongation. My reservation with doing it that way is that I don't have a baseline measurement. I would have to assume that the motor started out right at spec.
Why can't life be simple?

A good place to start is to measure the timing chain stretch the simple and less accurate way. Line up the TDC marks on the cam and read the number of degrees off the crank. It is generally accepted that this will tell you whether the stretch is something to worry about, it will not however tell you the precise amount of stretch. This is what I did and I got 2-3 degrees. I'm not worried.
