    E-TEC 170 Aluminum Cylinder Heads

    Feature 170cc Vortec-shaped intake and 65cc exhaust ports. Flow 20% more on the exhaust side than cast iron Vortec heads and produce power up to 6000 RPM. 64cc combustion chamber gives about 9.5:1 compression ratio with stock pistons in a 350.

    Technical Notes:
  • Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat.
  • Requires hardened pushrods. Recommend Edelbrock 350-9629 for flat tappet cams only
  • If using stock rockers, use .100" longer than stock pushrods.
  • Can not be used on engines with less than a 4" bore except with cams having less than .450" lift.
  • Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.
  • E-Tec 170 heads are 50-state street legal

    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.
