{"product_id":"long-tube-headers-big-block-chevy","title":"Long Tube Headers - Big Block Chevy","description":"The Hedman Hedders 68190 Standard Uncoated Headers are crafted in the USA from mild steel with a CNC mandrel-bent tube construction for smooth exhaust flow. The 1-3\/4 inch primary tubes and 3-inch collector are designed to maximize horsepower and torque for Big Block Chevy engines (396-454).\n\nHedman's unique gasketless ball and socket collector design simplifies exhaust system alignment and eliminates the need for a collector gasket. This set includes all necessary mounting hardware, gaskets for the cylinder head, and 2-1\/2 inch reducers.\n\nThese long-tube headers are intended for 1967-77 Chevy passenger cars. Specific applications include 1967-69 Camaros, 1964-77 Chevelles and El Caminos, 1968-74 Novas, and 1965-70 Bel Air, Impala, and Biscayne models. They are compatible with A\/C and various transmission types (automatic column\/floor, manual column\/floor).\n\n**Important Fitment and Emissions Notes:** Power steering compatibility varies by vehicle; specifically, there is NO power steering on Camaro and Chevy II\/Nova models. Additionally, these headers are not legal for street use on 1975-later model years and are for off-road use only. They are uncoated and ship with a temporary black paint that will burn off during operation.","brand":"Hedman","offers":[{"title":"Default Title","offer_id":52688656630072,"sku":"68190","price":337.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687903045.jpg?v=1784892389","url":"https:\/\/store.motormia.co\/products\/long-tube-headers-big-block-chevy","provider":"MOTORMIA","version":"1.0","type":"link"}
