Ok, I checked my assembly. I have the rockers with the offset groove and the tube on my rocker connector is the 3rd of the 3 styles pictured. I need a replacement rocker assembly (at least I believe I do) because my shafts are badly grooved at the far front and rear ends. Am I correct that if I find a 59-62 rocker assembly that I shouldn't need the drilled bolt...but I probably want to use one due to the fact that my head gasket is most likely sludged up?
