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 center bolt and\/or 1986 \u0026amp; prior perimeter flange mount valve covers and most stock exhaust manifolds.\u003c\/p\u003e\u003ch4\u003eSPECS\u003c\/h4\u003e\u003cdiv\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCNC Ported\u003c\/th\u003e\n\u003ctd data-th=\"CNC Ported\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCombustion Chamber Volume\u003c\/th\u003e\n\u003ctd data-th=\"Combustion Chamber Volume\"\u003e64.0 cu.in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDeck Height\u003c\/th\u003e\n\u003ctd data-th=\"Deck Height\"\u003e9.025 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDeck Thickness\u003c\/th\u003e\n\u003ctd data-th=\"Deck Thickness\"\u003e0.562 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eExhaust Valve Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Exhaust Valve Diameter\"\u003e1.600 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGuide Plates Included\u003c\/th\u003e\n\u003ctd data-th=\"Guide Plates Included\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eIntake Runner Volume\u003c\/th\u003e\n\u003ctd data-th=\"Intake Runner Volume\"\u003e200.0 cu.in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eIntake Valve Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Intake Valve Diameter\"\u003e2.020 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaterial\u003c\/th\u003e\n\u003ctd data-th=\"Material\"\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePush Rod Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Push Rod Diameter\"\u003e0.312 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRocker Stud Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Rocker Stud Diameter\"\u003e0.375 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eValve Angle\u003c\/th\u003e\n\u003ctd data-th=\"Valve Angle\"\u003e23 deg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eValve Spring Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Valve Spring Diameter\"\u003e1.460 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eValve Spring Maximum Lift\u003c\/th\u003e\n\u003ctd data-th=\"Valve Spring Maximum Lift\"\u003e0.575 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eValve Stem Diameter\u003c\/th\u003e\n\u003ctd data-th=\"Valve Stem Diameter\"\u003e0.341 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":67921973543006,"sku":"0E31C","price":1158.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0232\/4721\/files\/e914c4936312149299229ae8da62430e.jpg?v=1793751082","url":"https:\/\/slrspeed.com\/products\/edelbrock-e-tec-200-small-block-chevy-cylinder-head-hydraulic-roller-cam","provider":"SLRspeed","version":"1.0","type":"link"}
