Perfect for all high performance street/strip, racing, and marine applications, Trick Flow PowerPort® 320 cylinder heads for big block Chevy deliver exceptional power potential and competition level durability. Features include rectangular intake runners for strong mid- to high-rpm performance, fully CNC-profiled, heart-shaped combustion chambers, CNC bowl blended valve seat transitions, 24 degree intake valve angles with 4 degree side cants for additional airflow volume, adjustable guideplates, and premium quality, high-strength aluminum castings. The Fast As Cast® runners flow almost as much air as fully CNC-ported heads right out of the box. That means you’ll get almost CNC-ported performance for about the same price as regular cast heads.
Cylinder heads are available fully assembled or as bare castings. Sold individually.
