BRODIX BBC CNC HEAD HUNTER SERIES CYLINDER HEAD/24 2138102-2138105

The BRODIX Head Hunter series represents the cutting edge of conventional big block
technology. These heads are 100% CNC ported and utilize features such as raised, oval-shaped
intake ports that flow an amazing 465 cfm and newly designed exhaust ports that flow 308 cfm
with only a 1.850 exhaust valve. Standard features include an extra thick deck, high valve cover
rail, and the best castings in the business.
