{"product_id":"engine-cylinder-head-10","title":"Edelbrock Engine Cylinder Head for 1900 Chevrolet Big Block 60435","description":"\u003cp\u003eThese new cylinder heads are our latest addition to our popular Performer RPM 454-O cylinder heads for big block Chevy's with oval ports. These cylinder heads feature a 100 Cubic Centimeter chamber that is ideal for high compression applications. The unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat of the pants performance and crisp throttle response. Both the intake and exhaust ports have been profiled for improved air flow. They also have smaller than stock 11\/32 Inch valve stems for excellent flow and a lighter weight valve. The heat crossover passage is present, but has been blocked, making these heads not legal for use on emissions controlled engines.\u003c\/p\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":58355507593600,"sku":"BDVJ_60435","price":1367.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9390\/7840\/files\/ImageServerAPI_23439441-854e-482a-bc7c-d267422e9200.jpg?v=1783342254","url":"https:\/\/modridge.com\/products\/engine-cylinder-head-10","provider":"Modridge","version":"1.0","type":"link"}
