Small journal 327 main bearing question

[ChadW]

Building a small journal 327 and cam across some bearings I’ve never seen...I ordered from summit and they are the sealed power tri-metal main bearings..the oil hole in the bearings do not line up with my block oil passages..but these bearings also have a groove cut all the way through them that does line up with the passage..I called tech support and they assure me these are the correct bearings...anyone ever seen this before? Am I ok to use these?
