The term you’re looking for is “recommended”. Due to the higher volume and velocity of exhaust gasses exiting the cylinder heads it’s wise to equip the motor with headers, as well-engineered headers create a sort of suction effect where the exhaust gasses are pulled from the heads.
Your potentials for power gains will skyrocket with a solid aftermarket header, especially with ACE.
