SBC exhaust valve spring retainers
I am in the process of replacing the valve springs in a 91 5.7 TBI with COMP CAMS 981-16 springs and retainers. I bought the kit Comp Cams K12-249-4. The exhaust valve retainers have what I believe is a "rotator". Should this be reused in place of the new COMP retainer for the exhaust, or is it necessary?
