Manley 10868-8 Big Block Chevy Street Master Stainless Valves 2.250 11/32 +.250
Manley specializes in engine performance for everything from street to track to drag strip. Their product line-up includes valve train components, pistons, rings, connecting rods, and crank shafts for everything from late model V8’s to sport compacts. Manley Street Master valves are excellent-quality valves at an affordable price. All are made from stainless steel (intakes are NK-841; exhausts are XH-424) with chrome stems and hardened valve tips. Street Master series valves are fully machined and swirl polished, and both the materials used and the heat-treating process are superior to those of the Budget replacement series valves. They're available in a variety of head diameters, with either straight or undercut stems for increased flow. Order the set that's compatible with your vehicle and engine application.
