no doubt the banana grooves will improve oiling, and additional holes in the rocker too.
But not all 273's had banana grooved rocker shafts. Anybody know if slant six rocker shafts were grooved those things run forever?
So no emotions involved here so please don't get butt hurt but...
You started a post asking about this Then when people that know provide what your seeking you want to refute it That is your prerogative for sure free country and all that
but I'm guessing you have a semi-performance build in mind given you wish to maximize your camshaft thru an adjustable rocker setup
if you do actually have a six cylinder slug and it's a grocery gett'r then by all means use them as they are again your prerogative
but when your rocker train goes squeak squeak and turns blue please just look in the mirror for the answer "why".....
