Pontiac engines, but feature a CNC machined combustion chamber. The CNC machined chamber results in a consistent and precise chamber for improved flow performance. Performer RPM CNC cylinder head is available in two chamber sizes. The 87cc chamber version is ideal for 9.5:1 engines and will deliver excellent street performance on low octane fuel. The Edelbrock #61529 Performer RPM CNC cylinder head is patterned after the same port flange configuration as the 1969-1970 Ram-Air IV Pontiac Cylinder Head.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":62049426473331,"sku":"EDE61529","price":1539.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/6289\/0099\/files\/621d2f45e49a0b3e2100e598aad55c63.jpg?v=1756480885","url":"https:\/\/dspperformancemotorsports.com\/products\/edelbrock-cylinder-head-performer-rpm-cnc-pontiac-1962-1969-455-ci-v8-87-cc-combustion-chamber","provider":"DSP PERFORMANCE MOTORSPORTS","version":"1.0","type":"link"}
