Manley NexTek Valve Springs

These Manley NexTek valve springs are better-designed valve springs using state-of-the-art machinery for purpose-built racing engines. They're manufactured from super-clean, high-tensile chrome silicon steel and are shot-peened to MIL specs for maximum fatigue life. They feature a proprietary, multi-step heat-treating that minimizes load loss and have computer-aided modeling to minimize valve bounce and valve gear separation. The Manley NexTek valve springs are smaller diameter and lightweight, allowing engines to rev higher faster. They have an extended tip thickness designed to eliminate overload breakage, and their tightly controlled open-end flatness reduces valve stem side loading.

Trick Flow® PowerPort® 240 Cylinder Heads for Big Block Mopar

Once you see Trick Flow® PowerPort® 240 heads 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 in. 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 in. stainless steel valves, Trick Flow® by PAC Racing valve springs, chromoly and titanium retainer options, and 7 or 10 degree steel valve stem locks.
