SKU: TFS-41310001-M13

Serious horsepower for your Big Block Chevy engine, heads sold individually.
Trick Flow PowerOval® 280 cylinder heads for big block Chevy are an ideal upgrade from factory cast iron heads for street/strip and marine applications. They feature an oval intake port design that produces excellent low and midrange torque and horsepower, plus more efficient heart-shaped combustion chambers, .300" raised exhaust ports, extra-thick decks and walls for porting, and Fast As Cast® runners for near- CNC-ported performance at standard cast head prices. CNC bowl blended valve seat transitions promote high velocity and huge airflow volume and 24 degree valve angles with 4 degree side cants further increase airflow.
