Always check them, never had one that was dead on, or close to it, out of the box. A bit of a pain, but always a good idea to check and correct. When I get the bellhousing dialed in with offset dowel pins, I always drill and tap the block for small set screws so that the pins won`t get knocked out of position during bellhousing re & re . Obviously zero is ideal, but I try to keep it under .005".
