Spark Plugs

SPARK PLUGS: Use 14mm x 3/4" reach gasketed spark plugs. Heat range will vary by application and may range from Champion N-9Y to N-14Y (or equivalent).Use anti-seize compound on the plug threads to prevent galling in the cylinder head, and torque to manufacturers specification for aluminum heads.

Bye the way, this is quoted from Edelbrock's Performer Installation Guide which I am attaching.

What range recommendation for 302, mild cam?

With a propensity to foul, would you hotter or colder?
