Notes:
Fits engines with "Vortec-style" manifolds. Includes valve springs for use with hydraulic flat tappet only. To use stock rocker arms, 0.100 in. longer-than-stock pushrods are required. S/B Chevy heads may not be used on engines with less than 4" bore (262, 265, 283, 305, 307 c.i.d.) except with cams having less than .450" valve lift. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat.
Edelbrock E-Tec Cylinder Heads
Engineered for maximum performance, the new E-Tec Series aluminum cylinder 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 increased power. Available with 170cc or 200cc intake runners, these cylinder heads are assembled with one-piece stainless steel valves, 1.46 in. valve springs, retainers, and locks. The E-Tec models accept either centerbolt or standard valve covers, and work with most exhaust manifolds and headers. Match your vehicle specs to the correct Edelbrock head for precise fitment.
