Fully Assembled or Bare Heads

100% CNC ported intake, exhaust & chambers

Air Flow Research Eliminator "Race Ready" and "Competition" heads are composed of A356 aluminum castings that utilize premium grade components throughout, making the heads ideal for aggressive street/strip builds and race applications. The intake, exhaust and chambers are 100% CNC ported for better flow and performance including a 3/4" thick head deck. Multiple runner volumes and combustion chambers available for your preferred application. The exceptional flow characteristics, 23 degree valve angle, and standard valve spacing make these the perfect cylinder heads to use with conventional rocker arms. The perimeter bolt valve covers are standard, the exhaust port is race ported and is raised .250 over stock. Available for either standard or spread port exhausts with a choice of being fully assembled, as well as bare (without parts).

Notes

  • AFR strongly recommends using 7/16" rocker studs on SBC heads with todays fast cam rates and RPM capabilities.
  • SBC heads with 1.625" O.D springs will require some springs to be removed for access to some head bolts during installation.
  • SBC heads are designed for 5/16" .120" thick-wall pushrods, larger pushrods will not fit without clearancing.
  • AFR SBC 227cc heads have a "60/40" stud and valve location, shaft mount rockers are highly recommended, if Drag Racing you can run a .050" offset intake stud mount rocker with the AFR supplied guide plate, but the roller tip of the stud mount rocker will not be perfectly centered or sit squarely causing increased side loading and wear.
  • AFR LT1 heads are machined for both center and perimeter bolt valve covers, valve cover bolts must be shortened to 3/16”. These heads are not compatible with self-aligning rocker arms.
