well I am not sure exactly which spark plugs you need to get, but here is something from the instructions for your heads:
Spark Plugs: Use 14mm x 3/4" reach gasketed spark plugs. Heat range will vary by application from Champion RC9YC to Champion RC14YC.
The RC12YC is the plug used in the RPM applications (or equivalent). Use anti-seize on the plug threads to prevent galling in the cylinder
head, and torque to manufacturer's specification for aluminum heads.
Use that to start with. You might want to call edelbrock's tech line and give them your combo information and they might be able to recommend which plug in that range is best to use. Always go with the spark plugs intended or recommended for the heads.
