{"product_id":"sts-br7-bare-aluminum-cylinder-heads","title":"STS BR7 Bare Aluminum Cylinder Heads","description":"The Brodix STS BR7 264 LS7 Cylinder Heads are a high-performance upgrade for LS-style engines, offering enhanced durability and airflow. These bare aluminum cylinder heads are 100% CNC-ported, ensuring precision and optimized flow characteristics. The design features 264cc rectangular intake ports that flow over 375 cfm, and exhaust ports that flow 240 cfm. Each head is equipped with 71cc combustion chambers and utilizes a 12-degree valve angle for improved performance.\n\nThe valve sizes are 2.204 inches for the intake and 1.614 inches for the exhaust, with provisions for 8mm valve stems. The heads are sold as bare castings, meaning they do not include any internal components and require assembly with compatible parts.\n\nThese Brodix STS BR7 heads are designed to work with a minimum bore of 4.125 inches. As they are bare castings, users will need to source and install their own valves, springs, retainers, and other necessary valvetrain components. The product also comes with a PROP 65 warning.","brand":"GM","offers":[{"title":"Default Title","offer_id":52688568647992,"sku":"BRO-1178000","price":2783.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662664403.jpg?v=1784891146","url":"https:\/\/store.motormia.co\/products\/sts-br7-bare-aluminum-cylinder-heads","provider":"MOTORMIA","version":"1.0","type":"link"}
