SB Crane Retrofit Roller Lifter Issue

I finally got my block back and put the cam in for a test fit. The #3 exhaust lifter only covers the oil groove may .003"-.004" which does not seem ideal. The rest of the lifters have their oil grooves well covered, especially the right side where the main oil gallery resides. I did try switching the lifters around to see if that would make a difference and it didn't. What do you think?
