Just to be clear though......
All the factory 273 shafts, for use with the adjustable rockers, have the two sets of oil holes?
The set down near the bottom, and the set up near the adjusters?
And “some” also have the grooves on the lower holes?
None of the factory shafts for the adjustable rockers would only have the one set of lower holes like what would be used with the stamped hyd rockers?
