Trick Flow® PowerPort® 190 Cylinder Heads for Small Block Mopar
Trick Flow® PowerPort® 190 cylinder heads for small block Mopar engines are made from A356-T61 aluminum because it's much lighter but 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.
That's not all! 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 in. 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 in. stainless steel valves, Trick Flow by PAC Racing® valve springs, steel valve stem locks—and have chromoly and titanium retainer options.
The heads fit all non-emissions 318, 340, and 360 engines found in many Chrysler vehicles from 1967-2003. You read that right: these heads fit both LA and Magnum-series engines, giving builders a truly "best of both worlds" scenario. That means Magnum builders can use readily available LA engine parts such as intake manifolds and valve covers. PowerPort® 190 cylinder heads are available fully assembled or as bare castings; sold separately. Order the model recommended for your year/make and engine application.
