You'll need to have the seats machined out bigger to put the new valves in

I wish it was that easy...it needs precise cutting tools to get with in a predetermined tolerance of a size. Something stable...hands tools would never be precise enough. There is a correct tool and way to do this, id call up a machine shop because its fairly involved
