Asking NAPA might not be a good thing to do, because they will probably give you the number of a stock replacement, that will probably be incorrect. Make sure you have the proper thread length. Many aftermarket heads take longer than stock plugs. Stock heads take 3/8" reach plugs (Champion H series), while most after market heads I have seen use 3/4" reach plugs ("L" series Champion plugs). Too short a plug will be "shrouded", while one that is too long will interfere with the exhaust valve, causing a collapsed side electrode at best and engine damage at worst.

Perhaps someone on here has a more precise answer, but the make of plug is a personal choice, the length can be determined by screwing one into a head that's off the engine, but the heat range is best determined by experience. Edmunds heads have the spark plugs relocated so they can use extended tip plugs, but I think they are the only ones that can. resistor plugs are usually unnecessary, and the other variables are again, personal choice.

Edelbrock recomends rc12yc or rc14yc champions or equvalent. 14mm, 3/4” reach,flat gasket,5/8 hex extended nose. I like NGK plugs,but others work fine.

This number is wrong. Only 3/8” reach, need 3/4” For Edelbrock modern heads per the Edelbrock instruction sheet.

Autolite 3924 or Ngk BCP5ES interchange amoung others.

Just for comparison - I run NGK- B-4L for my 59ab - Navarro heads, Fenton cast headers and dual Stromberg 48's.

Do what you want, but I wouldn't use Champions. Quality is way down from their glory days.

To be clear, I wasn't recommending Champions, I was just using them as an example, because they were used by Ford in those days. As I said, brand is a matter of personal choice. That being said, I have a set of Champion L82YC plugs in the Edmunds heads on my '51 Merc and they have performed admirably.
