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. This head includes 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 a cast iron Vortec head, 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 head is dual-drilled and will accept 1987-95 center bolt and\/or 1986 \u0026amp; prior perimeter flange mount valve covers and most stock exhaust manifolds.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/4a79a5cfd680c885df3360513d2400db.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/a94f98a6cca627bead20d256b78521ca.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9466a4aa197052135c6270e963aecbbe.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003cul\u003e\u003cli\u003eThicker Deck Surfaces Than Other Brands\u003c\/li\u003e\u003c\/ul\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":42577614045278,"sku":"EDE60985","price":975.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0030\/5315\/8515\/files\/7d82ff6e7834baea5460635b193ad978.jpg?v=1774262255","url":"https:\/\/10secondracing.com\/products\/edelbrock-cylinder-head-sb-chevrolet-performer-rpm-e-tec-200-for-hydraulic-roller-cam-complete-ea","provider":"10 Second Racing","version":"1.0","type":"link"}
