No, it doesn't. It's not that hard, although it does mean removing Cam belt.

You can do it though, if you are very careful. Just mark the position of the belt on the pulley and make sure it doesn't move on the bottom pulley. Undo the 19mm nut on the Cam Pulley before you do anything (Car in gear and handbrake on etc). Mark the distributor position etc.

I'm sure you can get the cam out on an MFi RST but its been that long!! They come out easily when you're on EFi, but not sure about clearing the metering head.

When you remove it, you need to guide it out or it will 'clunk' along the cam journal bores and possibly cause damage.

I'd probably closely inspect the lobes with the cam in first. Establish in your mind which are Inlet lobes and which are Exhaust lobes and compare them. You should see a noticeable peak, which may not be visible on a worn lobe.
