SB Crane Retrofit Roller Lifter Issue

Working with a '71 340 block. Put new .550 lift Crane Hydraulic Retrofit Roller Lifter cam in and installed new Crane roller lifters. When spinning the cam around three lifters on the driver's side of the block look like they come too far up and expose a small portion of the lifter oil groove. This has me worried that oil will hemorrhage out and cause oil pressure issues. The oil groove is exposed just a hair, maybe .001"-.003".

What is the solution here? Different lifters, smaller lift cam? I bought the cam and lifters from Summit recently so they can be returned if need be.
