KA24DE Stainless Steel Valves
BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head.

KA24DE VALVE GUIDES
BC premium valves guides are made from Manganese Silicon Aluminum Bronze alloy and CNC machined to exacting tolerances. BC guides are resistant to cracking and corrosion, while reducing friction and insures high lubrication even at elevated engine temperatures and rpm's. The perfect replacement to worn or damaged guides and 100% compatible with BC's lineup of stainless steel valves.
