Chevrolet 3G Valve Cover and Cylinder Heads

Melling Performance valvetrain checking springs feature a low-tension design that allows them to be installed by hand for measuring piston-to-valve clearance, rocker arm ratio, and degreeing in a camshaft.

High Performance head bolts are available with a reduced wrenching hex or 12 point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing. All High Performance Series bolts are 180,000 PSI (which is 15 Percent stronger than Grade 8) and kits come complete with hardened parallel ground washers.

Product Features:

• High Performance Head Bolts Are Available With A Reduced Wrenching Hex Or 12 Point
• Wide Area Flanged Head That Eliminates The Need For Valve Train Removal To Facilitate Cylinder Head Retorquing
• Rated At 180,000 PSI Tensile Strength

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.

Product Features:

• Gasket bore – 4.035 inch: Compressed thickness – .040 inch
• Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
• Optimized sealing embossments seals extreme cylinder pressure
• Provides excellent stability and reduces cylinder bore distortion.

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

ARP only uses premium grade 8740 alloy and a proprietary ARP2000 alloy that are rated for superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000 material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.

If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in, you knew from the beginning that the rocker geometry was going to be inconsistent all over the place. ARP rocker studs are concentric within 0.005 T.I.R. thread pitch to thread pitch. They run in straight and true. Lengths are exact designed to provide positive seating every time. An extra large radius base offers greater resistance to flex. Available in both High Performance and Pro Series models. To be used with ARP patented Perma Loc(TM) adjusters.
