what smallblock solid roller lifters work without puting tubing in the block?

thought my old trusted lifters would work since they are fairly closed around the wheel even after changing to a new block without the tubes in the gallery but i gues i was wrong from my simple measureing it seams like they uncover the holes about 1.5mm
so what lifters should work?
i have a .570/.576" lift comp XE roller cam and i realy dont want to take my shorblock apart again just for this even if it feels nice to know i found it in time..
