Brodix BB-5 CNC Cylinder Heads (Factory Replacement for Mercury Racing 850Sci & 1075SCi (BARE HEADS)

These heads were designed by Sonny Leonard for the Mercury Racing's 850 & 1075 motors. They can be used on any Big Block Chevy that is 565 cubic inches or bigger.

The BRODIX -5 XTRA valve angles have been rolled 2° from stock to produce more torque and less chamber volume. The 5 XTRA also have a raised intake port design (approximately .400”) allowing the short-turn radius to have a better air flow angle without sacrificing velocity. Our competitors offer a similar version of these heads, but they have larger intake ports in the stock location. The competitor’s low profile head slows down the air speed making the engine extremely lazy.
When Sonny Leonard designed the -5 cylinder head for larger cubic inch engines, he incorporated the most important things: correct port shape, volume, and velocity. If you want to take the next step up from a standard valve angle cylinder head, the BRODIX -5 XTRA.
