how can you tell the difference...

The only thing you might be able to visually distinguish would be the longer duration (a little more lift too, iirc). It would have to be a side by side visual flavor test though. Turbo cam sitting next to the NA cam type of deal. The turbo cam would look slightly 'sharper' than the NA cam. There isn't a dramatic difference (visually or performance). That's probably why you haven't seen a universal movement of 7mgte owners switching to and advocating NA cams.

I believe the N/A cams and turbo cams were the same until 1990 or something like that. Might want to check to see what year car the head came off of.

Visually, the numbers should be stamped somewhere (usually on the front) of the camshafts. Lange's numbers should tell you exactly what you're looking at. You might have to pull the timing gears off to inspect the numbers, but they should be stamped right on them and in sight. Sometimes the stamping is light, so you may have to look closely.
Just print the list out and compare the part number stampings and it should tell you exactly what's up.
If you really want to know the numbers from the camshaft, you need a micrometer (not a dial caliper) and a degree wheel with a stationary indicator to check the following (which can be done easily on the head):
Degrees of advance from center line
Maximum lift
Duration
Degrees of lobe separation
I would suggest to anyone interested in learning about camshafts to pick up the newest month press (May2005) of Mopar Muscle and read the article on understanding camshaft numbers. It covers the basic proceedures of measuring the numbers of any camshaft to what each factor of the camshaft affects within the engines running characteristics. It's very well explained and easy for someone with no knowledge of camshafts to understand. Even if you're not a Chrysler fan, I would suggest picking the magazine up just for that article. It was very well written and in such a way that anyone with no understanding can become camshaft literate. It also explains what each measurment factors characteristic does to the engine and drivetrain and gives you a realy good idea about how certain numbers will affect your drivetrain. At least pick it up and read it!
