Didn't gap the plugs :-(

So I bought autolite 25's and put them in without gapping them correctly. The car fires up and runs good, so do you think that I need to take them out and gap them? What are they gapped at out of the box? I couldn't find anythign anywhere...and btw why did the pep boys guy tell me 25's over 764's?

Pull them out and gap them... doesn't take that long... then you won't worry/think about it.

My autolite 3924's come gapped to (what I guess to be about) 0.035. I run them at 0.054.

What heads do you run (just checking)?

At least pull one plug and check it so you can see what they came gapped at. I seem to recall having to regap 25's when I get them, so they might not be gapped quite right (I run 0.045" though, so maybe they are gapped right and it is my change that requires the gapping).

If you run alum heads, those are the wrong plugs and in any case, using neverseize is a good idea IMHO.

Good luck.

I run stock heads, and I just took the car for a test run and it seems to be pulling great. Even better than before with the bosch sparlk plugs that were in there from the previous owner. No backfire. I guess if something goes wrong its not hard to replace them for 8 bucks down the line.

I just threw some 25s in today and they were all gapped around .040 when I got them, I run .054. I don't want to give you bad advice on here but your car will probably run a tad better, you probably won't even notice it. When I first got my car each one of my plugs were gapped differently and the car runs as good as it does now. If you want to do the job right you can pull them all back out and gap them. But if your really not worried about it and don't want to do the job again just remember to do them next time a little down the road.
