Plug gaps

I'm going to replace the plugs in my 90 sc. I have Motorcraft platinum plugs 34FM. Are these any good, and what should they be gapped to?. Thanx.

the motorcraft plugs are probably the best for the SC. some ppl have had better luck with other plugs suck as autolites. i'd do .050-.054 if your stock. if you're running more boost than normal, gap them smaller than that. dont worry tho, a spark plug job is really not as bad as it looks. do the driver side from underneath and unbolt the compressor and move it out of the way for the passenger side. u can do the whole pass. side from the top. good luck !

Are the 34PP the original plugs for an SC? I know, stupid question, but I'm still new to the SC. My other toy is carbed, and alot easier to work on.
