he's saying the crank is an 85 so you need a 85 block??  he hasnt done many 22R's then.   tell him to match the thrust bearings to the block, the cranks are the same.
no matter how the hole got there its there. so you will need new pistons just make sure what block you have.  its easy the older blocks are 11.280 inches tall from oil pan to head,  the August of 84 and newer blocks are 11.080.  the timing chains and covers have to match the block and the heads are different also.

somebody post a picture of the thing on the side of the newer blocks
