Finally, the most user-friendly big block head on the market has been developed.

BRODIX is now manufacturing a cylinder head that bolts directly in place of stock cast iron heads allowing reuse of the intake manifold and pistons. The most important improvement is that the exhaust ports are in the stock location eliminating header or manifold interference.

The Race Rite® rectangular or oval port is the answer for less hassle during installation.
