small block engine priming

Who has run 273 rockers on there 360?

So I primed and turned engine over and primed and I didn't get no gusher like with stock rockers. I did this for over an hr. Many rotations of the engine. I got little trails from top hole, some of the rear holes oiled(not all) some dripped underneath. I even pulled one rocker shaft off to make sure oil holes where clean and clear. Do these rockers Just not use alot of oil or what? Almost makes me want to clearance my stock rockers and throw them in with some stock length pushrods. I don't see it oiling any better and i don't want burn up a new engine. This was also with 75-85 psi oil. rocker shafts are banjo shafts, they are also orientated correctly. notches down and to rear on passenger and forward on driver side.. any thoughts or is this normal? my factory rockers got plentyrockers.jpg rockers1.jpg rockers2.jpg rockers3.jpg rockers4.jpg of oil
