You could try switching to a heavier oil. I did that on my 91 Town Car when it was burning oil and it cut the oil consumption down noticeably. I went from 5W30 to 10W30. This was a common problem for these earlier 4.6 engines. Quite frankly, I wouldn't lose sleep over it. Mine was smoking pretty good at lights/stop signs just like yours and I was burning a quart to about 1300 miles. That was with about 120K miles on the odometer at that point. My dad had a 94 Town Car and it was burning about 1 quart every 600 miles. You couldn't tell by driving it though because it ran like a top at 200K miles burning that much oil.
I remember reading in my car manual a word from Ford specifically stating that if your car burns 1 quart to over 1000 miles, there is no need for concern. If it burns a quart to less than 1000, the issue should be addressed. My guess is that you will have a lot of miles on that car before it gets to the point where it should be addressed "by Ford's standards". At that point, why would you waste the money to re-do the valve seals. Just drive it and when she is a little thirsty, add more.
BUT, if you want to tackle the job, here is a tech article outlining the procedure. Nevermind that it is for a Town Car, the engines are the same. It's not really an overhaul at all, but it will take you some time.
