    E-TEC 170 Aluminum Cylinder Heads

    Edelbrock E-Tec heads are replacements for 302, 327, 350 & 400 c.i.d. S/B Chevy engines with ''Vortec-style'' manifolds. They feature an LT1-style raised runner intake port design for increased air-flow and ultimate performance. A unique combustion chamber design positions the spark plug closer to the center of the cylinder, promoting a more efficient combustion resulting in more power. These heads include an adjustable rocker stud and guide plate set-up for use with adjustable rockers or washers to properly position the stud height to accommodate factory style self-aligning rocker arms. They have 20% more exhaust flow than cast iron Vortec heads, great performance up to 6000 rpm and can produce 9.5:1 compression with stock pistons in 350 cubic-inch engines. RPM E-Tec heads are dual-drilled and will accept 1987-95 centerbolt and/or 1986 & prior perimeter flange mount valve covers and most stock exhaust manifolds. E-Tec 170 heads are 50-state street legal.

    Installation Note: To use stock rockers on S/B Chevy heads, .100'' 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.

    Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC. They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.

    Engineered to greatly increase performance and efficiency, E-TEC heads fit Small Block Chevy 302-400ci engines with ''Vortec'' style intake manifolds. These powerful heads incorporate Edelbrock's high-quench combustion chamber which promotes a more uniform atomization of the air/fuel mixture for more power. Spark plugs have been positioned closer to the center of the cylinder for more efficient combustion. Swirl-polished stainless steel valves provide maximum flow. They accept center bolt or standard valve covers, work with most stock exhaust manifolds and have intake and exhaust ports that are .200'' taller than typical Small Block Chevy heads. Match these heads with an Edelbrock Vortec intake manifold for the best results.

    E-Tec heads are dual-drilled and will accept 1987-95 centerbolt and/or 1986 & prior perimeter flange mount valve covers and most stock exhaust manifolds.

    Performer RPM E-TEC 170
  • 20% more exhaust flow than cast iron Vortec heads, good power up to 6,000 RPM
  • 64cc combustion chambers produce 9.5:1 compression with stock pistons on a 350ci engine
  • E-Tec 170 heads are 50-state street legal, E.O. Number D-215-49

    Performer RPM E-TEC 200
  • Outflow similar aluminum heads by 10% on the intake and 17% on the exhaust side
  • Make power up to 6,500 RPM
  • 64cc combustion chambers produce 10.2:1 compression with flat-top pistons in 350ci engines
  • CARB E.O. number pending

    Currently I am running a 350 ho 330 hp crate. I have a 142 blower onnot as well. I am looking to get more low end power. Are these heads a good choice for more low end power then the stock vortec heads that come with the motor

    Asked by: Frank w81
    This will require the use of a Vortec style intake manifold. I would suggest a different ratio pulley or different camshaft to change the power range.
