Bare Heads, No Parts AFR 377's are ideal for large cubic inch combinations, 540-615ci, that are looking for more airflow but want to retain a 2.300'' intake valve. This head will also work well on smaller very aggressive applications, like 489-532ci engines turning over 8000 RPM's. The 377 is very efficient and moves a lot of air early in the curve (415 @ .600'') making it an ideal choice if you're limited to how much cam lift you can run, such as a big inch marine engine with a hydraulic roller cam and a limited RPM ceiling. With close to 440cfm of peak flow, it should be extremely easy to clear 950HP in a single four barrel aggressive applications and even more in well sorted out combinations (especially with tunnel ram/sheet metal dual quad combo's). The exhaust ports are also notably stronger making the 377 an excellent choice in a forced induction or nitrous car that could benefit from the stronger exhaust flow. Of course the 377cc comes 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 377cc BBC. 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.
