BB-2, BB-2X AND BB-2 PLUS BB-2 305 cc INTAKE PORTS, 119 cc COMBUSTION CHAMBERS The BB-2 is the most versatile Brodix big block head. This head is recommended for use on a 427-509 engine with at least 12.0 to 1 compression. This is the best combination for a super comp. dragster with a 468 cu. in. engine. The BB-2 has ductile iron seats with solid phosphorous bronze guides that are replaceable. This head has a strong rocker boss and may be milled for a Jesel shaft system. All standard parts such as rockers, valve covers, intake manifold and pistons may be used. Spring seats may be cut, to 1.625 but no deeper. Longer head bolts or ten longer head studs must be used! The exhaust ports have been raised .600 higher than stock. The -2 may be angle milled to 108 cc out of the box or may be angle machined to 98 cc. BB-2X 340 cc INTAKE PORT, 119 cc COMBUSTION CHAMBERS The BB-2X head works best if used with a light weight car or a large engine (482-572 cu. in.). These heads will flow as well as 408 cfm at .700 lift. The BB-2X head may be purchased angle milled to 108 cc or angle machined to 98 cc. All standard rocker arms, pistons, intake manifolds, valve covers, and stud girdles may be used. A .250 longer than stock intake valve is required along with either longer head bolts, or ten longer head studs. The BB-2X has ductile iron replaceable seats and replaceable phosphorous bronze guides. The exhaust ports are raised .600 higher than stock.

BB-2 Xtra 365 cc INTAKE PORT, 119 cc COMBUSTION CHAMBERS The Brodix BB-2 XTRA is the best flowing cylinder head out of the box Brodix has made. The intake port flows over 375 cfm with only the bowls blended and the intake ports matched to the gaskets. The new 365 cc intake port has been contoured and matched for use on today's 500 cu. in. or larger bracket (super) racing engines. The combustion chambers are 119 cc and are properly shaped for use with either methanol or gasoline, thus preventing detonation. The beauty of this cylinder head is the fact that it accepts all standard pistons, intake manifolds, and rocker arms.

BB-3 370 cc INTAKE PORT, 119 cc COMBUSTION CHAMBERS The BB-3 has the largest intake port of all the conventional big block heads Brodix has to offer. We recommend that these be used on a 540-605 cu. in. engine. The BB-3 is not recommended to be used with a Jesel rocker system. This head requires longer head bolts or ten longer exhaust head studs. The BB-3 may be angle milled to 110 cc, but may not be angle machined! The BB-3 uses a standard intake manifold, rocker arms, and valve covers. The BB-3 exhaust valve has been moved .030 away from the intake valve. Brodix recommends that the valve pocket placement in piston be checked! Spring pockets out of the box, may be cut to 1.625 but no deeper. The exhaust has been raised .600 higher than stock. The BB-3 does require a .250 longer than stock intake valve and a special guide plate.

BB-4 340 cc INTAKE PORT, 134 cc COMBUSTION CHAMBERS The best application for the BB-4 is a 468-572 cu. in. fast bracket car with at least 13.1 to 1 compression and 7000 or more rpm. The intake and exhaust ports are raised for maximum flow. For proper installed height, use intake valve length 5.568 and exhaust valve length 5.495. By rolling the intake and exhaust valve over, the intake port is capable of flowing over 400 cfm. The BB-4 requires either special guide plates or a direct pedestal rocker made by Jesel or T & D. This head has ductile iron seats and solid phosphorous bronze guides. When using a standard height block, a tall deck manifold is required. If using a tall deck block, a tall deck manifold and intake spacers are needed. The BB-4 head may be angle milled into the mid 90 cc range. The spring pockets, out of the box, may be cut to 1.625 but no deeper.
