OEM Hydraulic Roller lifters / LA Engine

All the ones I've seen have that hole that must point to the inside (at the cam). If it doesnt have it perpendicular to the axle and you can't "point that hole up" you may get air trapped and ticking. The last set I used came from SIS I think... PAW sells/sold them. They have the hole in the right spot, but no paint daub like the factory ones do.
