//14° BIG CHIEF
To create the 14 Degree Big Chief performance cylinder head, MBE pulled together lessons learned from its winning NHRA and IHRA Pro Stock programs along with its 18 record-holding Comp Eliminator customers to develop ports that are perfectly sized to both maximize airflow and port velocity. With 2.470-inch intake valves and 1.830-inch exhaust valves installed in combustion chambers than can be sized anywhere between 72 and 84 cc’s, the precisely designed ports flow an astounding 535 cfm through the intake and 325 out of the exhausts. And remember, MBE is the only induction specialist willing to stand behind its advertised flow numbers with a guarantee that you will see the same or better performance on your own flow bench.
MBE’s 14 Degree Big Chief cylinder head is a great option for throttle stop racing, such as Super Comp or Super Gas and also works extremely well in nitrous applications. Some racers currently racing—and winning—with these heads include Vince Impastato and Artie Decesare in Top Sportsman. And more are using MBE’s 14 Degree Big Chief heads to join the ranks of the victors at the race track every week.
To squeeze the absolute most power out of your engine combination, MBE also produces a cast intake manifold custom ported to perfectly match the characteristics of the cylinder head. To put it simply, this is the best 14 Degree Big Chief cylinder head you can buy for big cubic inch engine packages (typically 565 to 700 cubic inches), especially if you need a head that keeps making power at rpm levels that are way beyond the point that the competition has flatlined.
