If you want the barrel to be "timed", putting the barrel roll stamps and sights, if there are sights installed, where they are intended to be, that will almost always cost more money 'cause it will take more time.
If you don't care where the roll stamps and sights, if there are sights installed, end up, a Remington 700 series barrel will almosts alway headspace correctly without any machine work. Or at least that has been my experience when installing them and I've removed and installed dozens of Remington 700 series barrels for myself and a few special friends.
