You can buy allen head brass set screws (I'm not sure which size you will need, they come in #4,#6,#8,#10 and probably #12 and maybe larger blank sizes (no holes in the centers) and then drill and tap the oil feed passage to the rocker shafts in the block or heads and then install the brass set screws and drill them to the size you want to use with a pin vise using small bits wrench up scope
