If you can live with "standard duty" Comp lifters and want pushrod oiling for a bb, and don't need offset pushrod seats, just use the AMC lifter(861) along with the bb mopar link bars(829L). These will have the same pushrod seat height as the 892(not 829) and 87016, but with the oil hole parallel to the axle.

Doug, your lifters have a "band"? Not slots like the ones in the pic?
Feed holes parallel or perpendicular to the axles?

On one of the motors I put together using Jesel rockers, I thought I'd be a smart guy and go with pushrod oiling. It was built from an aluminum World block with bushed lifter bores, so I got some Comp 892's for it. Had it all together, primed the motor....... And as soon as the drill bogged a bit from building oil pressure in the system, oil shot out of the top of one of the rockers 15-20 feet across the shop. Apparently, the hole in the bushing and the hole in the lifter were lined right up with each other when the cam was on the based circle. With the drill even barely turning oil just gushed out of whichever rockers were mostly closed. When I saw it my thought was, "well....... I guess that's not going to work". That was completely unrestricted oil flow to the top end.
Ordered some 87019's(no oil holes) and spray bar valve covers..... And that was that.

The lifters are on their way to Isky, so in about a week or so I should have some parts to test. Now to figure out why I have three relatively new intake rockers with busted needle bearing cages I've seen them break on the outer edge of the cage next to the snap rings, but these are all broken inside, where there shouldn't be any side load. I am glad I took the time to check them. They felt fine till I tried to rotate them a full 360 around the shafts, then I could feel some bind, and found the broken ones.
