This listing is for a single BRAND NEW Trickflow PowerPort Big Block Mopar 240cc cylinder head, TFS-61617802-C00 which include .680 max lift springs for hydraulic roller camshafts.
Serious horsepower for your Big Block Mopar engine, heads sold individually.
Trick Flow PowerPort 240 heads for big block Mopar are superior to stock and other aftermarket aluminum heads for several reasons. PowerPort 240 heads are made from premium grade A356-T61 aluminum because it is very strong and weighs a lot less than cast iron. The rocker shaft and runner areas have been enhanced to increase strength, and the oil holes for the rocker shafts were relocated to improve oiling. The shape of the runners was optimized to increase flow velocity and add much needed strength to the shaft bosses. The combustion chambers and runners are fully CNC Street Ported to guarantee proper dimensional accuracy and balanced flow from runner-to-runner.
Other 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 performed 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.
Trick Flow designed the PowerPort 240 heads to use all factory-style big block Mopar pistons, roller rocker arms, intake manifolds, and headers.
