Seems I have seen one of these before but is there any explanation as to why the last two numbers were stamped?

It was probably originally cast 1933198 but they needed more 163 intakes so the ground the 98 off and stamped 63. The only difference between the 2 intakes is the 198 intake has a milled out plenum divider.
