If the drop screws are digging into the block:
Lower them  :-)  or check the action spread. By moving these centers apart,
both the drop and let-off screws are lowered.

Was the hammer flange rail shimmed?

Have the balance rail glide bolts been cranked up to beyond maximum?

Is the bottom lamination or two of the block pushing downward (delaminating)?
