AFR 345cc Magnum BBC Cylinder Heads

If huge horsepower is what you're searching for, then AFR 345cc Magnum BBC cylinder heads will certainly deliver. They're recommended for radical street/strip, Pro Street, or racing applications on engines up to 572 cu. in. operating below 7,000 rpm—and are capable of flowing 400 cfm at 0.700 in. of lift. These A356 aluminum heads are designed for maximum horsepower and rpm capability, with an average primary operating range of 3,500-8,000 rpm; they also provide impressive torque figures. AFR recommends the use of .120 in. wall pushrods and full-roller rocker arms for strength.

It's vital that you check clearance of all moving parts due to the vast array of rocker arms, lifters, cams, springs, etc. Don't forget to check pushrod-to-head clearance, as well as any potential interference from your rocker arms and spring assemblies prior to final engine assembly. 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.
