{"product_id":"twisted-wedge-track-heat-assembled-cylinder-head","title":"Twisted Wedge Track Heat Assembled Cylinder Head","description":"The Trick Flow Twisted Wedge Track Heat cylinder head is an assembled performance component engineered for 289, 302, and 351W Ford engines. This head boasts 170cc intake runners, 2.02\" intake valves, and 1.60\" exhaust valves, complemented by 61cc CNC-profiled combustion chambers. Crafted from durable A356-T61 aluminum, these heads are specifically designed for track applications and are not emissions legal, making them suitable for off-road use only. They are capable of supporting naturally aspirated engines up to 600+ horsepower and are designed to work with camshafts up to 0.600\" lift.\n\nThe Twisted Wedge Track Heat series offers several enhancements over standard Twisted Wedge heads, including higher-rated valve springs, 10-degree machined steel super locks, and manganese bronze guides to support higher lift camshafts. The valve cover rail is raised 0.350 inches over stock height, and these heads are compatible with stock pistons and performance camshafts up to 0.550 inch lift. The construction includes ductile iron intake and exhaust valve seats, bronze alloy valve guides, and Viton® fluoroelastomer valve seals.\n\nInstallation difficulty for these cylinder heads is rated as difficult, requiring advanced skill. The product is explicitly noted as not CARB exempt and not legal for sale or use in California. It is designed for use with hydraulic roller camshafts, and requires drilling out head bolt holes to use 1\/2\" head bolts. Trick Flow twisted wedge pistons are also required for optimal use.","brand":"Trick Flow","offers":[{"title":"Default Title","offer_id":52664214323512,"sku":"TFS-51410004-M61","price":465.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687385017.jpg?v=1784335258","url":"https:\/\/store.motormia.co\/products\/twisted-wedge-track-heat-assembled-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
