Stage V 426 Hemi Aluminum Cylinder Heads

These customs heads are capable of supporting as much power as you can build around them. All Stock Hemi parts interchange and the original look has been maintained. Intake Seats: 2.25",Exhaust Seats: 1.900", Chamber Volume: 168 cc Not legal for use in NHRA Stock or Super Stock competition.

Typical applications include, muscle car restorations, sprint cars, ski boats, tractor pulling, hot street cars and drag racing where rules don't require "factory original" parts.If you are restoring a vintage Street Hemi powered Mopar but don't yet have an engine, consider these aluminum heads as an alternative to worn out used parts. Stage V heads look just like what originally came on your Street Hemi. Also, By reducing the angle of the exhaust valve from 23 to 21.5 degrees, we are able to fill these heads with monstrous 2.42 intake and 2.00 exhaust valves while retaining the stock rocker geometry. The larger valves enhance the already excellent flow characteristics of the Stage V Hemi head to the point where there is literally no automotive head in existence capable of coming close. An such as when engine displacement approaches the 600 cubic inch mark.
