Most of the time, on header flanges, they only have one hole that is to the right size, called a locator hole. The rest are bigger to allow for mis-aligned holes, and heat expansion.

i still lay out two holes.then i have used long body pointed set screws for threaded transfer . laying out the hole and finding center some times work s better then just a transfer punch what bears on this is how thick the pattern is
