If I'm reading the rulebook right any head run in SS/CS must be NHRA accepted. The list of approved heads on nhraracer.com doesn't include any Ford heads for SS/CS. What am I missing?

"All heads must be NHRA-accepted, two valves per cylinder, except in classes DS, ES, FS, and GS, four valves per cylinder permitted."
