As long as you don't have a MSD or Mallory ignition system, those types of Timing Lights are worth it. They have many features that are usable but they DO NOT work with multiple spark discharge ignition systems. My wife bought me one about two Christmas' ago, and it would work sporadically on my MSD ignition system. Checked both MSD and Mallory website and they both confirmed that any Timing Light with an advance feature will not work. Had to send it back and use my trusty Craftsman light that my father had since 1972.
I thought about just grabbing a Craftsman, but the newer ones seem to have terrible reviews...
Craigslist is your friend for finding good old timing lights that are built well and cost next to nothing. I was able to buy another Craftsman for $10 on Craigslist that is the same as my original. Last year, my fathers timing light bit the dust because I laid it on the air cleaner where it promptly fell into the cooling fan and met its demise.
Plain ol' Regular Unleaded
I've never seen plugs look like that either.
I mean, I'm no expert. But I've changed my fair share of plugs...
I should've been more clear. I mean is that 87 swill from the indian colony?
I've always run Shell or Chevron (premium when the funds allowed) and, although I had some pinkish stuff on there, they never looked like they'd been power coated.
You're also running the hottest plug and there's no evidence of it even trying to clean up, not even at the tip of the electrode where it's the hottest. I wonder if we should bring your ignition system up for review.
Any thoughts on an upgrade?

Get some colder plugs like Matt has above. AND DON"T LET THE COUNTER MAN TALK YOU INTO PLATINUM PLUGS.
Scrape out that RTV and install a e-core coil and adapt the distributor to take the larger Ford Cap. (I think it's called a Team Rush upgrade???)
I was going to shoot for cooler plugs, but someone (I forget who) was adamant about only running the recommended plug, so that's what I picked up (985's). Not sure how to determine the cooler plug numbers. I suppose they will be able to look it up at the counter.
And I thought the upgrade to the Ford cap was only for the V8's distributors...?
I could be wrong. I've read so many threads trying to figure this out, it gets confusing.
