These are floating pins, so I don't think narrowing them will help much. Thanks for the idea though. Tim

Not sure how much you could (safely) take off the smaller Hemi pin dia but you can shorten BB (1.09") pins 1/4" off each end & still (safely) maintain enough pin/piston contact area & will lighten it (these I have) from 191 to 159 grams if you have access to a lathe or if it would be cost effective for you to pay that shop time. Pressed fit of course
