{"product_id":"5-7-hemi-phase-6-ported-heads","title":"5.7 HEMI Phase 6 Ported Heads","description":"The Arrington Performance 5.7 HEMI Ported Heads - Phase 6 are engineered to maximize the performance of your HEMI engine. These are the top-choice Arrington Eagle 5.7 CNC ported heads, featuring upgraded valve springs, retainers, and locators capable of supporting camshafts up to .625” of lift.\n\nThe valve seats are meticulously single-point CNC cut with a Newen Epoc, utilizing the advanced designs and processes found in Arrington's Dodge P7, P8, and TRD Phase 14 Race Heads. Both intake and exhaust ports are smoothed and optimized using engineered, dyno-proven custom CNC methods developed by Arrington's in-house HEMI engine builders and engineers.\n\nThese heads undergo rigorous re-testing on custom-built, computer-controlled dynamometers and flow benches. The flow bench used is custom-built and operates with wet flow in the proper direction, unlike standard benches that flow into the combustion chamber. Titanium retainers are available as an upgrade for an additional cost.","brand":"Arrington Performance","offers":[{"title":"Default Title","offer_id":52686992900408,"sku":"API-PH6S","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662150814.png?v=1784879246","url":"https:\/\/store.motormia.co\/products\/5-7-hemi-phase-6-ported-heads","provider":"MOTORMIA","version":"1.0","type":"link"}
