Question Sparkplug help Trailing and Leading???

I need some help please. My '86 is flooded so I am about to begin the three step process. Went to the store today and bought new NGK plugs. Now I am sitting here with two boxes of "leading" and two boxes of "trailing" spark plugs.

What in the world am I suppost to do with these? What are they and which ones go where?

Already checked the plugs in the car. That's right...the numbers don't match.

Appreciate any help.

As for the unflooding procedure, follow this. http://www.rx7.com/tech/unflood-fc.html

4 Spark Plugs total. 2 Trailing, 2 Leading.
Trailing - 2 upper holes
Leading - 2 lower holes

Remember Leading for lower and Trailing for Top next time.

Thanks guys. Really appreciate it. Think I'll do the flooding process tomorrow before the Super Bowl. My neighbors will really appreciate the smoke in the area!
