Found some older threads on this subject:

• Correct spark plugs for a SV Ford CMP
• Ford V8 spark plugs
• Ford CMP Spark Plugs

And moved this to the Parts/Sources subforum.

Edited to add:

Brands and types listed in above threads:

• Champion H9, H10 and J10 - only the H10 cross refers to NGK B6L
• NGK B6L (and alternatives: BM6ES, B6ES etc.)
