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.

The Edelbrock No: 9710 Exhaust Valve Seat is a replacement for Edelbrock cylinder heads.

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.

This engine expansion plug is designed to match the fit and function of the original part on specified vehicles. Made of quality materials, it is engineered for reliable performance.

Edelbrock part No: 7310 head gasket is intended for Small Block Chevy Performer and RPM Heads. This gasket comes as a set and is for 1957-1985 engine sizes 283-302-307-327-350-400 without steam holes. This has a 4.190 bore size, .038 compressed thickness and 8.60 cc volume.

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.brbrA 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. Mr. Gasket provides a Limited Lifetime Warranty for MLS cylinder head gaskets.

The Edelbrock No: 5823 replacement mechanical roller Sure Seat Valve Spring for Edelbrock cylinder heads are made of highest quality spring wire and precision wound to close tolerances.

“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. ”

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.

All Pro Series bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and are rated at 200,000 PSI tensile strength. ARP Pro Series head bolt kits are application specific, designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP zero defect zero failure quality standard. Hardened and parallel ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12 point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more stretch to compensate for the additional compression of gaskets.
