Bare Heads, No Parts If huge horsepower is what you are searching for, this castings will certainly deliver. With the fully CNC ported 357cc flowing 425 CFM it can produce upwards of 900 HP. This cyilnder head was targeted at larger cubic inch engines, 509-632ci, 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, so higher reving 450+ cubic inches can benefit from the efficient runner. Blown, turbo, and nitrous engines will especially like the larger, higher flowing intake ports. AFR BBC 357cc 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. The 357cc come standard with AFR's trademark .750'' (3/4'') thick cylinder head deck, reinforced rocker stud bosses, premium one-piece stainless steel 2.300'' intake valves and 1.880'' exhaust valves. Standard combustion chamber volume is 121cc for the 357cc BBC and can be milled as low as 102 cc's if necessary. Take note the higher flowing exhaust ports and bolt pattern are raised .375'' (3/8'') over stock location, this rarely affects header or chassis fitment.
