2020 Chevrolet Corvette Valve Cover and Cylinder Heads

ACDelco GM Original Equipment Engine Valve Lifters automatically help maintain a ‘zero’ valve lash condition to help prevent valve train noise and unnecessary valve train component wear, and are GM-recommended replacements for your vehicle’s original components. These original equipment valve lifters have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:

• Adjusts the valves on your vehicle’s engine for proper performance
• GM-recommended replacement part for your GM vehicle’s original factory component

COMP Cams Pro Magnum Hydraulic Lifters are specifically designed to perform at higher engine speeds. When engines are equipped with conventional hydraulic lifters, high RPM is limited by improper positioning of the internal piston. Pro Magnum Lifters eliminate improper positioning and harmful “pumping up.” COMP Cams Pro Magnum Hydraulic Lifters offer a significant power increase over standard high performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used. An adjustable valve train is required to use Pro Magnum Hydraulic Lifters.

Product Features:

• .842″ diameter; 99g weight; 1.93″ seat height
• Specifically designed to perform at higher engine speeds with significant power increase over standard hydraulic lifters
• Proper position of internal piston at higher rpm prevents lifters form harmful “pumping up”
• Adjustable valve train required
• Pre-load lifters .002″-.004″ with engine warm

High Energy Hydraulic lifters have a patented constant orifice metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and pushrod seat is maintained, eliminating excessive oiling at high engine speeds. The pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength and wear resistance.In addition, High Energy Lifters have a lightweight check valve disc that allows for quicker response, which results in increased engine speed before valve float. This check valve disc also maintains added control at all engine speeds and loads.COMP Cams High Energy Hydraulic Lifters also contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity.

Product Features:

• .842″ diameter; 94g weight; 1.99″ seat height

Fel-Pro gaskets are specifically designed for the repair environment to deliver a reliable seal on even the most troublesome applications. Designed for imperfect sealing surfaces and manufactured with proprietary materials, you can count on Fel-Pro for innovative sealing solutions for the real-world repair environment.

Product Features:

• PROPRIETARY NEXTGEN COATING TECHNOLOGY – Precise amount of coating is applied to withstand higher engine temperatures and accommodate surface finishes as rough as 80 Ra
• UNIQUE COMBUSTION SEAL – Exclusive Laser Weld stopper layer technology reduces gasket damage from blow out and helps ensure a stronger combustion seal
• MULTI-LAYERED STEEL CONSTRUCTION – Multiple layers of stainless steel maintain sealing stress and accommodate head lift
• SUPERIOR SEAL – Precise embossed sealing beads at vital areas to eliminate leak paths
• DESIGNED FOR IMPERFECT SEALING SURFACES – Engineered and manufactured specifically for the repair environment to help seal imperfect sealing surfaces

Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids. A typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.
