Rocker oiling or lack of .

I am reassembling my engine after blowing a freeze plug and replacing bearings because I didnt like the look of them and I wanted to double check the oiling system due to what I considered insufficient flow to the top end.
Oil pump was gone thru , all galleys cleaned , cam bearings checked for alignment , cam holes verified, oil feed from cam to shafts checked for blockage ,HS rockers so orientation of shafts doesnt matter. Still no oil coming out when I prime it with 1/2 HD drill . Same as before the rebuild .
Here is the kicker... I am running Crowed severe duty HIPPO roller lifters with pushrod oiling as well ! I can see a little oil seeping from a few of the cups but this engine should be gushing oil from the top end !

What am I missing ?
