Hey guys, I am going to give my cruiser a tune up and was wondering what spark plugs are correct for my 64 F135 motor. They currently have the denso W16FS-Us in them but I read that the W14-U are the ones I need. Is this true? Thanks a lot.
What plug, W16FS-U or W14-U?

14m/m x 3/8
which I think are the 14-u
My oem owners manual claims w14 denso or ngk b4
The info I got from treeroot is:W16FS-U are the new nippndenso, W17P are the old nippondenso, although he's out to dinner with Algazy
difference being 3/8 or 1/2.. It probably doesn't matter but it'd be interesting to know if the 3/8 is that much better...
I have the ngk b5hs based on the w16... 1/2 reach. HUMM..
