If "Dirty Harry" drove a race car, then it would certainly be fitted with a pair of AFR 345 Magnum aluminum cylinder heads. If huge horsepower is what you are searching for, then these castings will certainly deliver. With AFR race-ready "as cast" 345cc heads flirting with 400 cfm. AFR 345cc Magnum BBC cylinder heads represent the ultimate in airflow for your big block Chevrolet. These cylinder heads were targeted at larger cubic inch engines (509-632 c.i.d.) looking for maximum horsepower and rpm capability with a primary operating range of 3,500-8,000 rpm (this range is an average and will vary with engine displacement and component selection). These aluminum heads also provide impressive torque figures at higher rpm levels. Blown, turbo, and nitrous engines will especially like the larger, higher flowing intake ports. These heads will work best with camshafts exceeding 0.750 in. gross valve lift to make better use of the substantial airflow found in the higher lift range. AFR 345cc Magnum BBC cylinder heads come standard with AFR's trademark 3/4 in. thick cylinder head deck, reinforced rocker stud bosses, and premium one-piece stainless steel 2.300 in. intake and 1.880 in. exhaust valves.
