I've read two topics here on PF and there are 2 different nrs that people discribe as 071 sparkplugs

first one is Motorcraft 071 AGPS071C finniscode = 1120834
second is Motorcraft 071 AGPR071C no finniscode

Wich one is the best to use??

0.7mm IIRC on std ignition but check first. Also it was suggested gapping them with the feeler gauge at a 45 degree angle.
