I wouldn't do anything other than thin the pushrod buldge as much as u can, opening it to the gasket at the port window entrance does not help cause the push rod pinch is still there right afterwards. See if the intakes port windows are wider to start, only open the them up to the divider wall part of the gasket is my advice...though if they are wider on the pinch side..then just open the heads window to them as is and no more.
