T CIS Heads with EFI?

Is it acceptable to modify the injector bung in my heads (2.4 CIS)to receive pulse injectors or should I just have the bungs plugged/welded?

The heads get too hot to allow for proper injector function.
Weld/plug the hole and install the injectors away from the heat preferably in something that is insulated from the heat.
Cheers

Thanks Henry! If I'm staying around the same displacement (looking at your upsize P/C) are the stock valve sizes ok or should I go bigger/smaller? Aside from normal r+r stuff is there anything else to do to these heads to prep for EFI?
