The Edelbrock 383-440 Mopar heads are the same as the Mopar "452"aluminum heads Mopar sells thru MP.They are made for Mopar by Edelbrock,and are legal for S/S.The 2012 Flyer has a part number and says they are legal heads.The Edelbrock heads typically are cheaper price wise than the Mopar 452 aluminum heads.

The Eddy and 452 Mopar heads have 2.14 I and 1.81 E valves whereas the OEM iron head are 2.08 I and 1.74 E.
