For over a decade now, our STEALTH aluminum cylinder heads have been hands down the best bang for the buck you can find! Capable of an easy 550 horsepower (when used with our 500+ inch stroker kits) these have the potential to make 650-700+ horsepower with port work and upgrades. Shown below are detailed pictures and specs on these exciting heads. Our Stealth Cylinder heads are rated as one of the Top Ten aftermarket Mopar parts by Mopar Collectors Guide Magazine!! Complete cylinder heads include Stainless Valves, Valve Springs, Valve Seals, Valve Retainers, and USA MADE Comp Cams Valve Locks. Heads are assembled and ready to bolt on the engine. Rocker arms & shafts, head bolts, valve covers, spark plugs, etc. are not included with assembled heads. This auction is for one PAIR of (two) heads. They will come fully assembled with valves, locks, springs, retainers, seals, etc as shown in the main picture. Clearanced for large diameter valve springs, our Stealth heads use factory type rocker arms and stock diameter shafts, so no special “high-dollar” offset rockers are required. Any rockers that work on a stock Mopar head will work on our heads. This includes roller rockers, or even stock type stamped steel rockers. Heat crossover is blocked off for increased performance. Factory port windows, exhaust and intake manifold locations make sure you can use any “off the shelf” intake manifold and/or exhaust manifold/headers without any fitment hassles or special “spacers” required. Made of lightweight aluminum alloy, one of these heads weighs only 22 pounds bare or 29 pounds complete with valves and springs. Large, free-flowing intake and exhaust ports look nicer “out of the box” than most port jobs you’ll find done to factory heads. Instead of casting the ports small (like the factory did) and having to port them yourself, we’ve designed the ports to flow out of the box, better than a “full race” ported factory head would. Port volumes are about 212CC’s on the intake and 72CC’s on the exhaust. Intakes flow about 280-290 CFM as cast, with the potential to reach at least 330 CFM or more with porting. Compare that to 215-220 CFM from even the best factory production heads such as 906’s or even 915’s! Larger 2.14″ and 1.81″ valve sizes also come standard. Combustion chamber is a “closed chamber” design, with quench area built in, so the benefits of running “tight quench” can be realized. As with any closed chamber head, pistons with a raised quench pad cannot be used. If you have any questions about your application or piston type, please give our tech line a call. Chamber size “as cast” is about 80cc’s. All standard factory mounting locations for alternator, etc are in place. Super thick 5/8″ deck surface ensures these heads have tons of meat in the deck to withstand high compression, nitrous, or to allow for plenty of milling. Use this feature to reduce the chamber size.. (great for getting high compression ratios AND great flame travel with a flat-top piston.) The straight (100% factory) spark plug location puts an end to hassles with header tubes fitting correctly, AND ensures the spark plug relief cut in domed pistons doesn’t require any modification. Exhaust bolt holes are are heli-coiled for extra strength, AND we’ve made them blind, so you can say goodbye to coolant leaking all over when changing headers or header gaskets.
