Head Hunter™ Series/23°


 
 

 


The BRODIX Head Hunter Series is only getting better. The three oval-shaped heads in this arsenal include a 229 cc intake port flowing 325 cfm, a 225 cc raised intake port flowing over 335 cfm, and a 234 cc raised intake port flowing over 345 cfm. Top in the 23° class, these heads come standard with all the finest qualities BRODIX has to offer: the toughest castings in the business, ductile iron valve seats, phosphorous bronze valve guides, and 100% CNC machining.
