Mostly stock 340 engine what Spark plugs

Im put so little miles on mine the last 3 years ebcause id lost interest the guy at the shop that does my inspections laughed at me..he said...you realize in the last 3 years you have put LESS than 100 miles on your car...and right before I "lost interest" I had done a "tune up"...It had just been so long id forgotten what the plug #'s were and id seen so much about other plugs I figured id ask for some numbers. Thanks all...you guys are making this much easier. I will have a lot more questions about SB's coming up.
