{"product_id":"chevy-5-7-vortec-v8-ohv-cylinder-head","title":"Chevy 5.7 Vortec V8 OHV Cylinder Head","description":"The ADV Auto Pro cylinder head is a direct replacement for Chevy 5.7 Vortec V8 OHV engines, specifically for casting numbers 906 and 062. Constructed from the highest grade cast iron, this cylinder head is engineered with thicker decks for enhanced strength and an improved flow design to mitigate cracking.\n\nKey features include hardened stellite exhaust seats, CNC-machined guides, and a precise 3-angle valve finish on all seats. This head comes fully assembled in-house, complete with new valves, valve springs, retainers, keepers, and valve stem seals, ensuring it is ready for immediate installation. There is no upfront core charge, but a $250 core charge applies if the original core is not returned within 21 days, provided the cores match the heads purchased.\n\nADV Auto Pro offers a 3-Year Unlimited Mile Warranty on this cylinder head, excluding High Performance heads. Proper installation is crucial for warranty validity. It is essential to use the recommended head gasket, ensure the cooling system (including hoses, water pump, thermostat, and radiator) is in good working order, and that the head sold comes with installed Heat Tabs. Removal of these tabs will void the warranty, as will overheating, indicated by the melted center of the heat tab. The warranty does not cover labor or any additional parts or costs.","brand":"ADV Auto Pro","offers":[{"title":"Default Title","offer_id":52686810087736,"sku":"906\/062","price":599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661655990.jpg?v=1784877014","url":"https:\/\/store.motormia.co\/products\/chevy-5-7-vortec-v8-ohv-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
