Oil dipstick tube install?

Before trying to install a new chrome one in my new stroker I measured it to see how much diff there was and found it was about .010" bigger than the hole. That's a huge difference so I carefully filed some of the chrome off then put it in a freezer for a couple hrs and when installing it I inserted a snug fitting long Phillips screwdriver in it, applied a little grease to the end and tapped it in place. Was still a tight fit. Hope I never have to take it back out.
