Default Spark plug HELP ASAP....

I need to get these numbers straight tonight or no racing for me tomorrow.
I have 2 crack spark plugs. So changing them out.
Heres the problem the ones pulled out are AC Delco 41-931 (25162487)
The ones I got from GM are AC Delco 41-985 (12571164)
I also have some NGK TR55 (3951) from autozone.

The two new ones I got do not match the old ones from the car. The bottom of the plug by the electrode is almost 1/8 bigger on the two new ones than the one from the car.
Which is the right one. HELP...

Dude, change all of 'em out. If not cylinder power may be unbalanced. Good luck at the races.
