If you have installed a new valley pan gasket any time recently, then the whole hole punching bit is not really needed. THey came out with those instructions with the turbo kits before they made the factory turbo engines. After the factory turbo engines came out, the valley pans were modified to allow for the increased oil flow from the factory turbo draining back through the valley pan and ford and all of the gasket makers eliminated the n/a part number for the valley pan and now only one part number exists so when you purchase a valley pan for either engine, you are getting a turbo valley pan..... HOWEVER if you still have an original n/a engine , then , yes, punch away.
