Scraping/Squeeling Noise in Engine

I replaced my resistor plugs with platinums, but it took awhile to get the last one out and replaced. I drove it for a day with 7 new and 1 old plug. Idle was not as smooth but not too rough.

Now with all new plugs, I hear an ugly high pitched scraping noise at start up. I immediately shut the car down and have not touched her since. It's a W126 with 163K and what I suspect to be an original chain. My search of the site seems to indicate timing chain and/or tensioner. I'd appreciate any input.
