Proform Part Number: 66864. Proform Billet Aluminum Shaft-Mount Rocker Arms Take your Buick valvetrain to the next level of performance with a friction-reducing roller rocker system—install a set of Proform billet aluminum shaft-mount rocker arms!
The holes in the shaft were not drilled correctly, one assembly would not bolt to the head with all 4 bolts.
I had to redrill the 2 center bolt holes to make them fit correctly.
