{"product_id":"engine-cylinder-head-135","title":"Engine Cylinder Head","description":"The Edelbrock #60107 Performer RPM NHRA Stock\/Super Stock Cylinder Heads are designed as a bolt-on performance upgrade for any 1967-91 AMX, Javelin or Jeep with a 343, 360, 390 or 401 AMC V8 engine. They include adjustable rocker studs and guide plates set-up for use with small-block Ford style adjustable 1.6:1 ratio rockers. The intake flange is dual-drilled to accommodate early and late model intake bolt patterns, covering 1967-91. Complete heads include larger than- stock valve springs to handle most high-lift cams. They feature stock location ports for compatibility with standard manifolds and headers. A direct bolt-on for 1970 and later engines with 1\/2\" head bolts, these heads include step-dowel pins for pre-1970 engines. Their dual-quench combustion chambers produce approximately 9.5:1 compression in 401 V8 engines. The 45 Deg intake seat angle offers improved mid- to high-lift flow over the stock 30 Deg angle.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":51375275147579,"sku":"BDVJ_60107","price":1588.95,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/3a0baa7c46595.jpg?v=1781939369","url":"https:\/\/performancepartscanada.ca\/products\/engine-cylinder-head-135","provider":"Performance Parts Canada","version":"1.0","type":"link"}
