Trick Flow® Twisted Wedge® Track Heat® 170 Cylinder Heads for Small Block Ford

Something great just got better! Twisted Wedge 170 cylinder heads now feature updated A356-T61 machined castings previously reserved for Trick Flow's 11R series heads, including a .625" thick deck for more power-making strength. The castings' billet-like appearance seriously increases the cool factor too. Twisted Wedge 170 cylinder heads have Trick Flow's pioneering Twisted Wedge combustion chamber to reduce valve shrouding and enhance high-lift flow. The design features altered 15° intake/17° exhaust valve angles, which tightens the combustion chamber for increased compression and improved piston-to-valve clearance. That allows the use of higher lift cams with stock pistons—even with the 2.020" intake valves! CNC-profiled combustion chambers with relocated spark plugs optimize combustion efficiency, and a choice of 58cc or 61cc combustion chamber volumes allow builders to dial-in the perfect compression ratio. High-efficiency, Fast As Cast® runners and a competition level, multi-angle valve job deliver near-CNC-ported power and airflow at cast head prices. Assembled Twisted Wedge 170 cylinder heads come with top-quality stainless steel valves, bronze guides, PAC Racing valve springs, thread-in 3/8" or 7/16" rocker studs, and chromoly retainers to ensure great durability and longevity. Some Twisted Wedge 170 cylinder heads are emissions-legal under CARB E.O. #D-747-1 for 1996 and earlier Ford 289, 302, and 351W engines. Cylinder heads are available fully assembled or as bare castings. Sold individually.

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.

FLOTEK 290cc Big Block Chevy Cylinder Heads

FLOTEK's 290cc big block Chevy cylinder heads with 112cc combustion chambers are recommended for moderate street or street/strip BBCs with displacements up to 509 cu. in. operating at or below 6,500 rpm. It may be necessary to check clearance and slightly modify some domed aftermarket pistons due to the efficient heart-shaped combustion chamber on these heads (most of the newer designed dome profiles will clear). FLOTEK recommends removing material from the piston and not the cylinder head, as the combustion chamber shapes are very critical to flow—altering the cylinder head can unfavorably affect flow and power performance. FLOTEK's medium-sized 290cc oval port cylinder heads are designed for 3/8 in. pushrods with 0.120 in. wall thickness. They're available assembled or bare for a variety of engine applications. NOTE: This item is not sold as a pair; this is a single cylinder head.
