If "Dirty Harry" drove a racecar, it would certainly be fitted with a pair of AFR BBC 345 "Magnum" cylinder heads. If huge horsepower is what you are searching for, either of these castings will certainly deliver. With Race Ready "As Cast" 345cc flirting with 400 CFM, these cyilnder heads represent the ultimate in airflow for your BB Chevrolet. These cyilnder heads are targeted at larger cubic inch engines (509-632 CID) looking for maximum horsepower and rpm capability with a primary operating range of 3500-8000 rpm's (This range is an average and will vary with engine displacement and component selection). As well, these aluminum heads provide impressive torque figures at higher rpm levels. Blown, turbo, and nitrous engines will especially like the larger, higher flowing intake ports. Our 345cc cylinder heads will work best with camshafts exceeding .750 gross valve lift to make better use of the substantial airflow found in the higher lift range. They come standard with AFR's trademark .750" thick cylinder 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 115cc's on the "As Cast" pieces and 121cc for our 345cc CNC Chamber. Properly selecting the correct cylinder head depends on a large number of variables.
