{"product_id":"genx-185-assembled-aluminum-cylinder-head","title":"GenX 185 Assembled Aluminum Cylinder Head","description":"The Trick Flow® GenX® 185 cylinder head is engineered to deliver performance comparable to CNC-ported heads at a more accessible price point, making it an excellent upgrade for naturally aspirated GM LT1 engines. Its design incorporates standard resolution CNC profiled combustion chambers (54cc) to enhance performance and retains the factory compression ratio.\n\nThe heads feature a 21° valve angle for both intake and exhaust, which increases piston-to-valve clearance and unshrouds the combustion chambers for improved airflow. Key specifications include a 2.020\" intake valve diameter and a 1.600\" exhaust valve diameter, with a maximum valve lift of 0.600\". The intake runner volume is 185cc and the exhaust runner volume is 67cc, with rectangular intake ports and D-port exhaust ports.\n\nConstruction materials include a durable aluminum cylinder head, chromoly steel retainers, and bronze valve guides, with ductile iron valve seats. The assembled heads come with intake and exhaust valves, valve springs, damper springs, retainers, locks, valve stem seals, rocker arm studs, and guideplates, ready for installation. These cylinder heads are sold individually.","brand":"Trick Flow","offers":[{"title":"Default Title","offer_id":52689428873528,"sku":"TFS-30410008-M54","price":1024.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687738288.jpg?v=1784906527","url":"https:\/\/store.motormia.co\/products\/genx-185-assembled-aluminum-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
