Leak in the Head Gasket

Bad news. Water and oil really do not like each other. High temps from big miles will just make it worse.
 
Do you like the car and care if you destroy the engine? - If it's bad enough to notice, I suspect it won't make it 3 1/2 hours.
 
Don't bother, the car may overheat. You'll crack or warp the head, and end up with a ****** engine.

Get it fixed!
 
Depends entirely on the severity of the leak and where it's leaking. A slight weep of coolant to the outside edge of the gasket is unlikely to cause issues as long as you keep the coolant level topped up. If the coolant is getting pressurised with combustion gasses or the oil and coolant are starting to mix already then not really a great idea.
 
Bad idea and i would not do it.

But if you need to drive it put this **** in there

Worked for me too - it let me drive a Mondeo with a dodgy head gasket to a dealer 120 miles away where we promptly px'd it for an Astra ;) Also put in in my Scorpio Cosworth to cure a weeping water pump gasket - it was good for three years until the water pump needed replacing at 100k miles (they almost always go at 100k on these cars - it's uncanny).

It might stop the head gasket leak, but it will clog up the channels in the radiator ;)

Not k-seal - as above - it was in the Cossies cooling system for 3 years with no adverse affects.

K Seal doesn't do this IME, at least not if the radiator/heater core are in decent condition to start with. If they are already clogged up then it's not going to help matters.
