These heads feature fully CNC-ported intake and exhaust runners, ensuring greater consistency and flow compared to many other high-flow Pontiac cylinder heads. Butler Performance has conducted extensive testing, including flow bench, dyno, and track tests, to achieve excellent performance numbers.\n\nThis comprehensive package includes a pair of Edelbrock wide port heads, fully built by Butler Performance. It comes complete with .040\" Cometic head gaskets, matched intake gaskets, T\u0026amp;D shaft mount 1.65 ratio rockers, Crower offset solid roller lifters, and ARP head studs. The heads also feature polished chambers and slotted pushrod holes to accommodate the included rockers.\n\nProper intake manifold selection is crucial, as the wide port heads require an intake with sufficient port height for matching.

The product includes stainless intake fasteners and a pushrod length checking tool.","brand":"Butler","offers":[{"title":"Default Title","offer_id":52687324643640,"sku":"BPI-TEP-WP-72SR-370","price":9799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661667084.jpg?v=1784882697","url":"https:\/\/store.motormia.co\/products\/wide-port-370-cfm-cylinder-head-pair","provider":"MOTORMIA","version":"1.0","type":"link"}
