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":51210970431803,"sku":"BDVJ_61529","price":2474.17,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/96e6fee10a284.jpg?v=1777678326","url":"https:\/\/performancepartscanada.ca\/products\/engine-cylinder-head-102","provider":"Performance Parts Canada","version":"1.0","type":"link"}
