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.
