A friend gave me these plugss - Champion N14Y. I know a lot of the YBlocks used F14Y. Any one know what these plugs are for? Hotter or colder F14Y????

If I remember correctly "N" was a gasketed type plug not a taper seat like the Y Block uses.

The "14" refers to the heat range.  The "Y" means extended tip.  I think the N has a 3/4" long, 14mm thread.  Length in inches, diameter in mm.  What were they thinking?  I believe they were for early bb chev, possibly other applications.
