OK, I changed four plugs on my new 1987 560 SEC. I started on the passenger side. I had to wrench them all the way out, they were a bit tight. When I got to the the other bank, I started on the first one, loosened it from the seat and it got real tight, could not back it out. Didn't want to break it so ran it back in and quit.

Talked to a friend of mine, a good indy, and he told me to just take it out. So, do I use a long breaker bar to back them out or what? I do have a thread chaser to use after they are out. Is this the best way to go?


BTY, what is the firing order?

Thanks
