Trick Flow High Port® 192 cylinder heads for small block Ford are one of the most dominant aftermarket heads in racing. They feature unique valve spacing, .750" raised exhaust runners, extra strong castings and thick decks for additional rigidity and gasket integrity, superior cooling characteristics, and most importantly, excellent airflow. And that’s not all! The entry into the intake runner has been reshaped to help seal the area along the port roof and thicker port walls increase strength and provide more material for porting. Plus, interlocking ductile iron seats are used to handle the stresses of high heat, high horsepower applications. Other features include fully CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending), raised valve cover rails, and large Fast As Cast® runners that duplicate the profiles of CNC-ported heads to create ultra high-flowing heads without costly CNC-porting.
