Trickflow PowerPort Small Block Mopar 190cc CNC Ported Bare Cylinder Head Casting, 60cc Chambers

Horsepower fans know that Trick Flow is all about developing products that provide maximum performance, such as the PowerPort® 190 cylinder heads for small block Mopar. The heads fit all non-emissions, LA and Magnum-series 318, 340, and 360 engines used through 2003. That’s right, even Magnum owners can now use readily available LA engine parts such as intake manifolds and valve covers.

Like all of Trick Flow’s top-quality cylinder heads, the PowerPort 190 heads are made from A356-T61 aluminum because it’s much lighter but still every bit as strong as cast iron. The intake runners have been enhanced to increase airflow, and both intake and exhaust runners feature Trick Flow’s special CNC Street Ported treatment that combines premium quality CNC machining with a standard resolution finish that‘s perfect for making more power. Newly designed rocker arm shaft mounting bosses are stronger than the OE design, and larger diameter pushrod holes have been incorporated to accommodate 3/8" pushrods for use with flat tappet and hydraulic roller camshafts. Bronze alloy valve guides, ductile iron valve seats, and multi-angle valve seats further increase performance and durability. Assembled cylinder heads include premium 11/32" stainless steel valves, Trick Flow by PAC Racing valve springs, steel valve stem locks, and have chromoly and titanium retainer options. Cylinder heads are available fully assembled or as bare castings. Sold individually.
