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. Since swapping cylinder heads can be a costly and time-consuming process, Trick Flow® designed the PowerPort® 240 heads to accomodate all factory-style big block Mopar pistons. They are also manufactured to accept aftermarket roller rocker arms, intake manifolds, and headers. They are available fully assembled or as bare castings. Sold individually.

BTR Canted Valve LS Cylinder Heads
What happens when you combine two lifetimes of cylinder head research and development? Why, BTR canted valve LS cylinder heads, of course! When you have a cylinder head casting legend like Rick Smith on board (father of the Hi-Port, A460, Twisted Wedge, and more) and decades of Brian Tooley's porting and cylinder head flow bench experience, you end up with serious game-changing performance! There are no other low-cost premium cast all-American canted-valve LS cylinder heads on the market, because only BTR put NASCAR-proven canted valve tech into the LS head and made it attainable. By rotating the intake 5 degrees and exhaust 3 degrees, these heads can achieve impressive intake flow with the BTR in-house port program. They use regular Gen 3 and 4 LS1 pedestal-style rocker arms/bolts, valve covers, and manifolding. They also use Gen V LT valves, spark plugs, and valve spring packages to make building them out easy with OEM-compatible parts. If you have a street machine or a racing class that allows a canted valve head design, BTR canted valve LS cylinder heads are the advantage you have been waiting for! More product details, items, and notes include: * Ships fully machined and CNC ported with finished valve guides and seats installed * Assembled units feature LT1-style valves installed to correct height with their 0.660 in. lift platinum spring kit, making them ready for your stock type LS1 rocker arm setup * For unassembled units, you can choose to use OEM-type LT1 valves or LT4 Ti Intake and L8T Inconel exhaust valves as an upgrade for higher rpm/severe duty * BTR exclusive canted-valve design allows for maximum valve unshrouding and sizing (LS1-style cathedral ports fit a 3.780 in. bore; LS3-style D-ports fit a 3.820 in. bore) * Degrees - 11 intake (5 degrees canted) and 13 exhaust (3 degrees canted) * LS1-style cathedral port finished to 250cc (chamber finished to 63cc) * LS3-style D-port finished to 260cc (chamber finished to 64cc) * LS1-style intake flow - over 360 cfm at 0.650 in. lift when used with the BTR port program * LS3-style intake flow - over 370 cfm at 0.650 in. lift when used with the BTR port program * Uses OEM LT1 2.125 in. steel hollow-stem intake and 1.590 in. steel exhaust valves * LT4 Ti intake and L8T Inconel exhaust valves can also be used with lash caps * Superior OEM-style powdered metal guides * Utilizes OEM-style straight LS1 pedestal rockers, OEM-style intake and exhaust manifolds, and LS-style valve covers * Uses Gen V LT style long reach spark plugs and valve spring kits with up to 1.350 in.
