I don't have the answer, but from another thread from someone that is using them, "To use the HT2148 lifters, cam base circle must be at least 1.135” diameter".

If that is the case, anything less than 1.135" base circle would allow the lifter oil feed hole/band to drop out of the bottom of the lifter bore.

Lifter oil feed hole protruding out of the lifter bore at the top at full lift shouldn't be an issue unless the top of the lifter bore has an excessive chamfer from the factory.
