Avenger 184cc Aluminum SBC Cylinder Head

Holley Performance Products is proud to introduce the latest addition to its line of aluminum cylinder heads for 305, 327, and 350ci small-blocks built up to 1986. The Avenger heads are cast 356 aluminum, heat treated to T-6 for strength and then CNC machined to exact tolerances. A .500-inch deck thickness was designed into the casting to give maximum strength and to improve gasket retention. All rocker stud and exhaust manifold bolt holes are heli-coiled for added strength and durability. The Avenger heads offer a 20-degree valve angle design to help optimize the intake and exhaust runner flow, but still retain the stock port locations for intake manifolds and exhaust headers. The heads come fully assembled with one-piece stainless steel swirl polished under-cut 2.02-inch intake valves and 1.60 exhaust valves; hardened steel guide plates; ARP rocker studs; and Lunati valve springs, locks, and retainers capable of handling the high-lift camshafts. The port-matched 184cc intake and 68cc exhaust runners are port-matched to ensure maximum flow, horsepower, and torque. In most cases the Avenger heads can be interchanged with factory heads. The 68cc combustion chambers are performance-designed to keep compression ratios down for use with pump gas, and the spark plug location has been optimized for better combustion.

Cost: $1,400 (MSRP).
