{"product_id":"boogieman-aluminum-heads-70cc","title":"BoogieMan Aluminum Heads 70cc","description":"The Cad Company AF85400 BoogieMan™ Aluminum Heads represent a significant upgrade for high-performance 472 or 500 Cadillac engines. These heads are built using American-made castings, precision CNC machining, and top-of-the-line seat and guide machines, offering the best available cylinder head for these Cadillac engines. They feature a 70cc combustion chamber, which adds approximately half a point of compression compared to stock 76cc iron heads. The included 2.25″ intake and 1.8″ exhaust valves are made from high-grade stainless steel, utilizing the same production methods as their iron head valves.\n\nThese heads are designed for impressive flow numbers across the entire valve lift range, achieving 402 cfm at 0.850″ lift while maintaining strong low-lift flow. Various valve options, including SS, Titanium, or Inconel, are available to suit different performance applications.\n\nA key feature is the raised and extended intake ports and raised exhaust ports. This means that even a stock intake might not fit under a flat Eldo hood or in other applications with limited clearance. The exhaust ports have also been raised, and the flange redesigned for a better seal with more bolts. Consequently, some headers may not fit, although Cad Company's off-the-shelf headers are generally compatible. The exhaust ports also feature a spread-out 3-bolt pattern for superior sealing in high-end applications.\n\nThese heads have been proven in a wide array of applications, from daily drivers to full race setups. They are capable of producing engines with 500 HP (with a mild cam) up to naturally aspirated full race engines exceeding 800 HP. Even on milder combinations, they deliver more low-RPM torque than ported iron or other off-the-shelf aluminum heads for big Cadillacs. For even higher performance levels, further porting and larger valves can be utilized. The engineering is the result of extensive research and development by Cadillac engine performance experts.","brand":"Cad Company","offers":[{"title":"Default Title","offer_id":52687329034552,"sku":"AF85400","price":3090.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661174997.jpg?v=1784882746","url":"https:\/\/store.motormia.co\/products\/boogieman-aluminum-heads-70cc","provider":"MOTORMIA","version":"1.0","type":"link"}
