Is this the cc306 ? Grind: 306 Lift: .555''/.555'' RPM Range. It is called Comp Pro-Magnum 306s. I am guessing that it is the cc306. If this is true then will it pass emissions?

 

cc306 has .510/.540 lift on a 1.5r ratio. That is probably a custom grind cam on the magnum series lobes. What are the duration numbers?
