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.

AFR 325cc Magnum BBC Cylinder Heads

Are you looking for big torque and horsepower numbers? AFR's 325cc Magnum big block Chevy line of medium-volume intake runners will provide you with exactly that.

From a max-effort high-compression 454 to a 605 c.i.d. low-rpm marine application, these aluminum cylinder heads would be a great choice. AFR Magnum heads would also be ideal in larger cubic inch Pro Street applications with their broad torque range, as well as their significant rpm and horsepower capabilities. These cylinder heads will work best with a primary operating range of 3,000-7,000 rpm (this range is an average and will vary with engine displacement as well as component selection). These 325cc heads come standard with AFR's trademark 3/4 in. thick head deck, reinforced rocker stud bosses, and premium one-piece stainless steel 2.300 in. intake and 1.880 in. exhaust valves.
