I have wd45 with a 4" bore dome piston in it.  It is a 1956 model. Did 45's come with 4.125 bore?  I also have a LP block with letters GH on end of # stamped in block. This one also is only a 4" bore with a high comp. piston in it. So can someone answer my question. Did someone  put these in the motors or did they come that way.

The  LP45s came with WD pistons for the 7.2 comp. I put  them in my 45 years ago with the overbore. I believe they are the dis low compression pistons. I do not think any WD pistions were dished.
