AFR 385cc Fully CNC Ported Magnum BBC Cylinder Heads

AFR is proud to announce our all new 385 cc Magnum head….the largest and highest flowing BBC product in our line-up with flow numbers that are creeping up on many of our competitor’s 18 degree raised runner Pro-stock style heads. If you’ve got the displacement we have the head to feed it with an intake port that achieves an incredible 455 CFM by .900 lift and clears 450 CFM as early as .800, however with over 440 CFM’s available as early as .700 lift, a large cam isn’t neccessary to make big power. We compliment that impressive intake flow with a 345 CFM exhaust port still maintaining a 75% or higher exhaust to intake relationship. While this huge runner is more clearly aimed at 572 - 632 CID applications, in a light car it could still be considered in 555-565 CID aggressive applications that are built to reliably turn 7800 - 8500 RPM’s. This head of course comes with AFR’s trademark .750 thick head deck, reinforced rocker stud bosses, and is equipped with 2.350 intake and 1.880 tulip exhaust valves.
