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..

I used the new Comp roller lifters that are made to just drop in. They did not uncover the galley even with a .700+ lift cam.

thats very impressive! is that with a full base cam or a reduced one? ok i gues i will look into those lifters, they are the ones with the linkbar on the inside if i remember right?

Morel makes some also. you can get them thru erson cams.

I'd order from Brian - ou812 as he helped/did the design. I did anyway.

Doug Herbert lifters drop right in also. Thats what I run. I paid $219 for them but I think they are like $239 now. You just turn them around so the link bar is against the lifter valley. My cam has a .640 lift and Ive had no problems. Ive been running them for several years now.

i wouldnt mind ordering from Brian he for sure seems like a very good guy to deal with, i just dont know how to get the money to him since i honestly dont own a visacard or anything like that

Don't have the part # in front of me, but our Comp rollers in our stroker 340 have cracked in several of the bodies. Roughly 53 passes on the combo. Not sure why, moderate cam, decent spring psi, no "at the moon shift point" (6700 iirc...) good pushrods. A strange harmonics perhaps?? who knows. I'm quite certain we're going to give the ones Brian has a try though.
