Are you looking for big torque and big horsepower number? Our BB Chevy line of medium volume intake runners will provide you with exactly that. The phrase " having your cake and eating it to" would certainly be appropriate with their moderately sized intake runners producing tremendous flow figures across the entire lift range (Our CNC 335 flows 410 CFM!). These high flow/high velocity ports provide extreme versatility and fill the needs of many applications. From a max-effort high compression 454 to a 605 CID low rpm marine application, either one of these aluminum cylinder heads would be a great choice. These heads would also be ideal in a larger cubic inch "Pro-Street" application with their broad torque range, as well as significant rpm and horsepower capability. These cylinder heads will work best with a primary operating range of 3000-7000 rpm's (This range is an average and will vary with engine displacement as well as component selection). Both the 325cc and the 335cc come standard with AFR's trademark .750" thick head deck, reinforced rocker stud bosses, and are equipped with premium one piece stainless steel 2.300" intake valves and 1.880" exhaust valves. Standard combustion chamber volume is 119cc's on our 325 "As Cast" pieces, while the fully CNC ported 335 version comes with a 121cc chamber. Both are available with an optional 114cc combustion chamber as well. Properly selecting the correct cylinder head for an application depends on a large number of variables. Please consult with one of our sales technicians to assist you in making the best decision for your particular application.
