The engine would be powerful enough to make the clutch slip when worked hard in my experience.

In theory you can make any clutch slip when worked hard.

If it's your daily driver then I strongly recommend the 266 with 1275 motor. If you're looking for a bit more grunt at the top end then the 266 with higher lift rockers works well.
I don't know how much power this would be down on the 286, but the torque up to about 2500rpm will be much stronger with the 266, where it's useful in traffic.
And the 266 will give you much better mileage.

In turn that means a lower final drive ratio is needed which will reduce cruising speed, or put the same cruising speed at higher revs.
And yes, you'll need a stronger clutch diaphragm.
A 286 is a far from ideal road cam due to the high revs needed to make it work. With a 286 the engine will need rebuilding much more often due to the high wear rate caused by the constant high revs.
