  • We strongly recommend using 7/16" rocker studs with todays fast cam rates and RPM capabilities as 3/8" Rocker Studs can occasionally break.
  • Heads with 1.625" O.D springs will require some springs to be removed for access to some head bolts when installing the heads.
  • Heads are designed for 5/16" pushrods, Larger pushrods will not fit without clearancing and is not recommended since some areas are very thin. AFR recommends the use of .120" thick-wall pushrods.
  • AFR 227/235cc Heads: Due to the "60/40" stud and valve locations, shaft mount rockers are highly recommended, however if you're ONLY Drag Racing you can run a .050" offset intake stud mount rocker with the AFR supplied guide plate (exhaust will use a standard rocker). Please note that with the .050" offset rocker arms the roller tip of the stud mount rocker will not be perfectly centered and will not sit squarely on the valve causing increased side loading and wear. This option is not recommended for race/endurance applications and/or street engines that see a lot of miles.
  • AFR LT-1 / LT-4 / Vortec Heads/ Late Model TBI/TPI Heads - Your factory accessory bolts and center bolt valve covers need to be shortened 3/16" or they will bottom out. These cylinder heads are machined for both center and perimeter bolt valve covers, please see your instructions to avoids oil leaks.
