Limiting the amount of coolant flow leaving the engine lets you control the amount of heat absorbed by the coolant itself. You can adjust the flow with one of these water outlet restrictor kits. They include include three round aluminum plates with 5/8 in., 3/4 in., and 1 in. I.D. holes. Simply mount the appropriate plate under the water outlet on the intake manifold.

HP Series Cylinder Head Studs - Small Block Chevy

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 re-torquing. All High Performance Series bolts are 170,000 PSI (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.

Premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). All kits come complete with hardened parallel-ground washers and high quality nuts. ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!
