Pro-Action 24-Degree BBC Cylinder HeadsDeciding which cylinder heads to purchase (and which configuration) can make or break your wallet. You can breathe easier now with big-block cylinder heads from RHS. With a standard 119cc combustion chamber, you can order these 24-degree heads from RHS in any arrangement to meet your racing needs. Purchase these heads as a bare casting with radiused and hardened valve seats, manganese intake valveguides, and phosphorus bronze exhaust guides. Or buy them assembled out-of-the-box with valves. If weight is a priority for you, RHS also makes these heads in aluminum. Both castings (iron and aluminum) are made with extra-thick deck surfaces for strength and machining. To avoid hot spots, RHS specifically designed these heads with a highly efficient water jacket design for better thermal conductivity. Whether you choose the 320cc or 360cc intake-runner length, RHS claims these heads will outflow the competition by 5 percent due to their superior as-cast port and chamber finish quality.

Deep Chrome PolishCleaning chrome surfaces can be a delicate process. Users must be careful not to further scratch the surface of the chrome by using traditional multimetal polishes, which can contain abrasives to cut into the surface of many metals, including aluminum or brass. However, Deep Chrome is specifically designed for chrome only, can be used very aggressively, and will never scratch the surface of your precious chrome.
