Edelbrock E-Tec Cylinder Heads are replacements for 302, 327, 350 \u0026amp; 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 cylinder heads are dual-drilled and will accept 1987-95 centerbolt and\/or 1986 \u0026amp; prior perimeter flange mount valve covers and most stock exhaust manifolds. INSTALLATION NOTE: 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 small-block Chevy heads, .100\" longer than stock pushrods are required. Edelbrock pushrods #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.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":40597464613043,"sku":"EDE60989","price":936.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/3758\/1491\/products\/aea18d273ecfee68d53a4eee54a775a0.jpg?v=1631980215","url":"https:\/\/hellhoundperformance.store\/products\/edelbrock-single-sbc-etec-200-head-comp","provider":"Hellhound Performance","version":"1.0","type":"link"}
