I would want mine faced in. I just installed a set of new HD lifters in a friends 07 SG and they had the oil Holes directional also. these hole went the the front.
I know this is an old thread but figured I throw in my experience to maybe help someone else doing this.
I just happened to be pulling mine a few minutes ago when I stumbled on this thread and they are different now on the 103s I guess.
oil passages on the rear cylinder lifter sleeves are at the back of the hole facing forward and the lifter oil passages were facing the holes, being rearward.
oil passages on the front cylinder lifter sleeves are at the front of the hole facing to the rear and the lifter oil passages were facing the holes, being forward.
As Doc pointed out I don't think it really matters, but I'll put them back in the way they came out.
