What spark plugs should i use 66 dart 170 base 2.8L engine?

I run Champion N14Y in both my 1965 -170 and my 1966 -225.I've run them for the past 40 years . It is the proper heat range for this motor. So,you're in the city driving a Dart,cool . ! I'm out on the island .Got lots of stuff for them .
Hey man, yeah I'm here in Astoria. She gets lots of smiles per gallon around here.
