Stupid question...what situation/combo requires pushrod oiling? Or is just a preference?
The stuff I've messed w/ has all been conventional oiling. Paired T and D individual shaft rockers need pushrod oiling. Gotcha...no other way to get oil to the other 3 shafts if they are separate, unless you have spray bars. The B1 motors I've messed with were common shaft w/ T&D rockers. Spray bars in the valve covers seem like a simpler solution, but I guess they aren't as effective? I've always liked the fact that my KB block doesn't oil the lifters. After 14 years I've had no issues, but my cam isn't aggressive either.
