Gents,
I've been rebuilding a 67 convertible with my teenage son for the last year and we're finally getting around to putting the engine back in the car. I can't figure out what spark plugs I should use. The engine block is a 302 (from 1973 I was told) with heads from a '75? (stamped A3B), an Edelbrock 289 Performer intake manifold, and an Edelbrock Perfomer 600 CFM 4bbl carb (#1406). The plug threads are 14mm. Won't be racing -- just enjoying some weekend drives. Any suggestions?
thanks!

After reading up on VMF, that's actually what I bought first, but I had to return them because they're 18mm and don't fit in the 14mm plug hole.

Thanks. I was overwhelmed by the variety of choices in reach, gap, heat rating.... I'll go with what you suggested. Appreciate it!
