Info

Direct bolt-on heads for Small Block Chevy 302, 327, 350, and 400 Stock and Super Stock racers. No port profiling or bowl blending of ports.

  • Out-of-the-Box Bolt-On Performance
  • Hand-Blended Intake and Exhaust Bowls
  • CNC-Matched Intake/Exhaust Ports in Std Location
  • Thicker Deck Surfaces than Other Brands

Edelbrock E-Tec cylinder 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. Cylinder head will 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.

Notes

INSTALLATION NOTE: Match with Edelbrock head gasket sets. 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. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat. To use stock rockers on S/B Chevy heads, .100" longer than stock pushrods are required. Edelbrock pushrods #9629 325-9629  are recommended. Use Head Bolt Kits for easy installation. 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.
