Edelbrock 60989 E-Tec Cylinder Head
Aluminum, Assembled, 64cc Chamber, 200cc Intake Runner, Chevy, 302, 327, 350, 400
Engineered for maximum performance, these new E-Tec series aluminum heads fit all small Chevys with Vortec-style intake manifolds. They incorporate Edelbrock's new high-quench 64cc combustion chamber design, which promotes a more uniform atomization of the air/fuel mixture for more power. Available with 170cc or 200cc intake runners, they're assembled with one-piece stainless steel valves, 1.46 in. valve springs, retainers, and locks. The heads accept either center bolt or standard valve covers and work with most exhaust manifolds and headers.
