COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.

Since their release, Jesel Sportsman Series shaft rocker arms have proven themselves to be the ultimate replacements for inadequate stud rocker assemblies on OEM and aftermarket cylinder heads. The 2024 aluminum bodied rocker arms are designed to withstand open spring pressures of up to 900 lbs., while maintaining precise valve lash settings. They are designed to bolt on with little to no cylinder head modifications and in most cases still fit under a stock valve cover. The rocker geometry is preset and engineered using the common valve supplied with the specific cylinder head to provide a bolt-on-and-go installation. If you're still spending aggravating hours adjusting your stud rockers only to have to repeat the procedure the next weekend, Jesel Sportsman Series shaft rocker arms are your solution. Choose a set designed for your application.

Trick Flow® GenX® 260 square port cylinder heads for GM LS7 are the best choice for your LS-based performance build for several reasons. The A356-T6 aluminum castings feature more material for increased rigidity and strength. Factory LS7 port locations, valve angles, and valve locations have been maintained to work with existing intakes and pistons. One-piece modular, 2024-T4 billet aluminum rocker arm mounts enhance valvetrain stability and are removable for shaft rocker setups. High flow, high velocity CNC Competition Ported runners with the premium high resolution surface finish provide all-out air flow and performance throughout the entire powerband. Plus there's clearance for 3/8" pushrods and through-deck coolant holes that fit all GM LS gasket and block combinations, Trick-Alloy™ powdered metal valve guides, and solid stem valves. Fully assembled heads also include Trick Flow® by PAC Racing Pacaloy valve springs, steel or titanium spring retainers, die forged steel valve locks, and stainless steel valves. Trick Flow® GenX® 260 cylinder heads are emissions-legal under CARB E.O. D-747 for 2006 to present GM vehicles with 7.0L engines. They are available fully assembled or as bare castings and sold individually.

Trick Flow GenX® 235 cathedral port cylinder heads are fully CNC-machined to significantly improve the performance of extreme street and race LSX engines. Trick Flow engineers altered the valve angles from 15° to 13.5° to decrease valve shrouding, increase mid-lift airflow, and improve rocker arm-to-valve cover clearance. Top-of-the-line CNC Competition Ported runners have a premium high resolution surface finish for maximum flow and performance. The spark plugs were relocated in the CNC-profiled combustion chambers to enhance mid-lift airflow and increase the rigidity of the casting for extreme horsepower applications. Material was added at the rocker arm mounting points to increase high-rpm valvetrain stability. Trick Flow GenX 235 cylinder heads are emissions-legal under CARB E.O. #D-747 for 1997-present GM vehicles with 4.8L, 5.3L, 5.7L, and 6.0L engines. They are available fully assembled or as bare castings. Sold individually.

Building on the features that make the GenX® 255 for GM LS3 great—like 12° valve angles and relocated valves for reduced valve shrouding and improved piston-to-valve clearance—Trick Flow's GenX® 280 HIP cylinder heads withstand the abuse of high horsepower, power-adder performance demanded by today's racers and engine builders. The GenX® 280 heads list of features is long, and it starts with the HIP'd (Hot Isostatic Pressed) castings. This process significantly increases the casting's density for improved tensile and fatigue strength. It continues with industry leading airflow through CNC Competition Ported 280cc intake ports and Trick-Alloy™ powdered metal valve guides for added longevity. Manley Severe Duty intake valves and Extreme Duty Inconel exhaust valves are designed to withstand the abuse of extreme temperatures and stresses of big power adder applications. Trick Flow® by PAC Racing dual valve springs, titanium retainers, .750-inch thick deck, and 6-bolt-per-cylinder mounting pattern round out the features. Trick Flow® GenX® 280 HIP cylinder heads for GM LS3 work with all LS3 intake manifolds and LS9/LSA blower assemblies and fit all LS head gasket and engine block combinations. These cylinder heads are available fully assembled or as bare castings. Sold individually. Key features: * 280cc intake ports and 67cc combustion chambers * HIP'd casting * Accepts 3/8 in. pushrods * Powdered metal valve guides * 2.165 in. NK-844 severe duty stainless steel intake valves * 1.600 in. XH-432 extreme duty Inconel exhaust valves * .750 in. thick deck * 6-bolt configuration * Assembled heads include a Trick Flow® LS3 rocker stand
