SB Crane Retrofit Roller Lifter Issue

I did look into the Comp Cams roller lifters. Comp says the specs are 1.425" from the bottom of the roller wheel to the top oil groove line. The Cranes are 1.427" so if I went with the Comp lifters I would have .002" more oil groove coverage. I don't think its significant enough for me to mess with. So I am going to run what I have since all the oil grooves are covered. I have been asking around and have been told there shouldn't be any problems by a few very knowledgeable engine builders.
