Welcome to the GWOF from PA.
As a mechanical person and someone who does their own maintenance, I would not use a stop leak unless absolutely necessary. Sometimes it's a very simple thing, like either a radiator cap, or the coolant reservoir.
Not telling you that you are wrong to do so, but just offering an opinion. If it is an intake manifold, it will be a lot of teardown which is why it will be costly, but if you are mechanical it is not a hard task.
