{"product_id":"5-7l-hemi-eagle-cnc-ported-cylinder-heads","title":"5.7L HEMI Eagle CNC Ported Cylinder Heads","description":"The 5.7L HEMI CNC Ported Eagle Heads are performance-engineered components designed to optimize airflow and combustion efficiency for the 5.7L HEMI engine platform. By utilizing proprietary CNC porting on both the intake and exhaust ports alongside precise hand-blended bowls, these heads offer a streamlined path for gases, which is critical for high-output engine builds.\n\nTechnically, these heads are prepared to a high standard, incorporating a multi-angle valve job to improve seat seal and flow characteristics. They are supplied fully assembled with new seals, shims, and moly retainers for durability.\n\nInstallation requires either the submission of your own 5.7L HEMI cylinder heads for reworking or the selection of a core exchange option, which carries a refundable core charge. Customers should note there is a 3-5 week estimated lead time on this service.","brand":"Modern Muscle","offers":[{"title":"Default Title","offer_id":52689273291064,"sku":"MMP-5709CNCHD","price":2322.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687907725.jpg?v=1784904419","url":"https:\/\/store.motormia.co\/products\/5-7l-hemi-eagle-cnc-ported-cylinder-heads","provider":"MOTORMIA","version":"1.0","type":"link"}
