Crower seems to have some issues with there .903 lifters IISKY are great but have seen a lot of sizing issues, One build took 3 sets to make up one set. I don't send any block out the door unless I have lifters in hand to fit.
Jesels and Morels seem to a great lifter and so far never had to send any back because of sizing issues.
