360 Motor Stock Pan HV Pump

The motor had a deep pan and a hv pump, i wanted to replace the pan only. Seeng i dont deep the depth but wanted to keep the hv pump, during the time i was putting back on the standard pan i noticed the hv pump was coming into contact with the back of the pan..... just a small amout... I wanted to ping out a small amout on the pan for the pump to clear the back of pan. Or shoudl i replace the pump with a stock pump, not sure if the stock pump will make a better clearence. I know that the hv pump is a little taller but not sure if that is the fix seeing it hitting the back.... Let me know what you guys would do.
