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 LT1 heads are machined for both center and perimeter bolt valve covers, bolts must be shortened to 3/16”. These heads are not compatible with self-aligning rocker arms.
Using a high volume or high pressure oil pump can submerge the valve seals in oil causing smoke or oil consumption.
Use full roller rocker arms, roller tip rockers with stock style bodies are NOT recommended.
