Mfg Part # 66864. Take your Buick valve train to the next level of performance with a friction-reducing roller rocker system. Premium Race Series rockers include 16 billet aluminum roller rockers with adjusters, two shafts, and all the necessary spacers and mounting hardware.
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.
