AF85141 Factory Replacement Aluminum Heads

These are the evolved version of the old Bulldog aluminum heads. They have 76cc combustion chambers and include 2.19 / 1.90 stainless valves, and weigh in at 38 Lbs. per head, vs 62 Lbs. per head for your average iron head.

Performance wise, they fall in between our Pro Street and Pro Comp 76cc iron heads. These are a good choice for medium performance levels, where saving weight is more important than bottom end torque, such as lightweight drag cars and gearbox airboats, but you aren’t going for maximum power. CNC porting is available, if you need more airflow, but don’t have the room for the extra inch of intake height the Boogie Man heads will give you, but they will still not be in the same league for power output.
