DESCRIPTION:

The 18 Degree Big Block Next Generation head is different than any other 18 degree head available. This head is so advanced compared to anything else out there it literally creates an unfair advantage on the race track. The intake ports flow an incredible 488 cfm through 2.420-inch intake valves—the largest used in the industry--while the exhausts move 326 cfm out of the combustion chambers. And remember, MBE is the only cylinder head specialist willing to guarantee its advertised flow numbers with your money back if you don’t see the same results on your own flow bench.

MBE uses its own proprietary casting because the Next Generation cylinder head is so radically different than anything else out there. By raising the valve spring pockets 0.500 of an inch, MBE was also able to raise the roof of the intake ports an equal amount. This allows vastly improved port flow while also narrowing the over the short turn to maintain ideal port velocity.

All conventional big block cylinder heads have two “bad” ports, which always flow significantly less than the other two ports. Besides reducing the amount of air and fuel you can get into the engine, this difference in the amount of flow also makes these engines difficult to tune for maximum power. But the Next Generation cylinder head not only eliminates the “bad port” phenomenon, the flow in the weakest port of this new head exceeds the very best of the “good” ports from conventional heads by 10 to 13 percent! Average flow across the board is as much as 40 cfm better than anything else out there. And because all four intake ports in the Next Generation head flow within one percent of each other, engines upgraded with these heads are easier to tune for peak performance.

Besides the revolutionary ports, MBE has also moved the intake guide bores from the traditional locations. This helps reduce shrouding with the extra-large intake valves and mid-lift flow numbers for improved horsepower and torque all the way through the rpm range.

A unique one-piece rocker bar draws on the best designs from Pro Stock Drag Racing and utilizes 16 fasteners to securely lock it to the cylinder head. The design provides unparalleled stiffness and valve control for improved valvetrain life and a higher redline than you will get with any other cylinder head.

And if you want the ultimate in power production, MBE also offers its own ported intake manifold that’s designed specifically to work ideally with this unique cylinder head. Together, they are practically an unfair advantage over the competition.
