It is not a restricter, it only has a wall thickness of about .025"-.030", made of brass usually, if you use the one you have with a 3mm hole, you may starve the head of oil.
If the one you have fits in the to block nice and snug and slides into the head nice. (should normally stay in the block and not the head) just drill it out, you will need a little lathe to do this properly. It should also only need to be about 4mm of it protruding from the block when fitted, and have a small chamfer on it as well.
