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 #61525 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":51210977018171,"sku":"BDVJ_61525","price":2536.54,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/8860b0ede0186.jpg?v=1777678499","url":"https:\/\/performancepartscanada.ca\/products\/engine-cylinder-head-110","provider":"Performance Parts Canada","version":"1.0","type":"link"}
