I've had this same issue with just about every mfg of lifters. What they say the lifters are like and what they actually ship are sometimes two different things. The catalog will say pushrod oiling and bushing oiling but when you get them you can see that they don't work that way.

I've had this issue with Crower and Comp. These days I don't believe anything the mfg tells me. I just order one pair of lifters and check them over and then order the rest of the set.

My guess is that most of the mfgs don't understand how a Mopar oiling system works so they just ship stuff that works in a Ford or a Chevy and call it good. Crane seems to be the exception. I've talked to the folks at Crane a few times and they actually seem to understand how to make a Mopar lifter. Not so sure about anyone else. Maybe Morel knows how to do it??
