I'm wondering if it's because I used aluminum for the head spacer, if I need to torque down the bolts down more, or if it's because there is a lot less surface area between the head and Z slide. I'll look into it a bit more tonight if I get a chance. Otherwise it's going to be Sunday night before I can look at is again.
