Once you see Trick Flow's PowerPort 240 head for big block Mopar in action, you'll agree they are the only aftermarket aluminum heads worth using on your engine!
What makes PowerPort 240 heads so great? For starters, they're made from premium grade A356-T61 aluminum. That's important because it weighs a lot less than cast iron and is very strong. Trick Flow engineers then fixed the shortcomings of the factory head design by relocating the oil holes for the rocker shafts and optimizing the shape of the runners to increase flow velocity and add much needed strength to the shaft bosses. Fully profiled combustion chambers and CNC Street Ported runners guarantee proper dimensional accuracy and balanced flow from runner-to-runner for maximum power potential.
Additional advantages of PowerPort 240 heads over stock heads include clearance for 3/8" pushrods, ductile iron valve seats, bronze alloy valve guides, and multi-angle valve seat machining on precision Serdi equipment. Assembled cylinder heads come with premium 11/32" stainless steel valves, Trick Flow by PAC Racing valve springs, chromoly and titanium retainer options, and 7� or 10� steel valve stem locks.
Since swapping cylinder heads can be a costly and time-consuming process, Trick Flow designed the PowerPort 240 heads to accommodate all factory-style big block Mopar pistons, roller rocker arms, intake manifolds, and headers
