Welcome mate.
1) What symptoms do you have that lead you to believe HG has failed?
2) LPG wouldn't make much difference. It burns a bit hotter, so isn't a good lubricant. It can wear valves over a VERY long time, but I doubt it would affect the HG.

Hi
try compression test
ps: also your car must loose coolant..

...not if the gasket is broken between two cylinders...

Which VERY rarely happens on modern gaskets with metal fire rings.

I suppose it depends how long it's been on the car. No6 cylinder fire ring rotted though, at the back though, on my Senator at around 150k & c10 years.

Thats unlikely to be cylinder to cylinder....they often fail when the coolant rots the supprting composite material away and the fire ring no longer has any support resulting in the fire ring pushing out towards the coolant ways.

i have taken the car back to wear i had it converted to LPG, they have informed me that the head-gasket had blown (as it had white smoke coming out of the exhaust). According to them, they have said that the LPG conversion has not caused this. Has anyone else had the same problems?

It's not often you're wrong Mark, but, as usual you're right again! :y

Are you sure its not just condensation? Is the car using any water?

Yes but it can happen >:(
lol ;D ;D

Not a good diagnosis if thats all they went on......this time of year any lpg car will chuck steam outa the exhaust esp when the engine hasnt fully warmed up. In this weather steam comes outa my exhaust on idle even with a hot engine.
What makes you think the head gasket has gone?

As TD says, not a conclusive diagnosis for a start. Does the car misfire on both fuels? What other symptoms are present? Water loss? Poor compression? Fumes in expansion tank? They should have checked these...
I think it would be unlikely for them to admit to the possibility that the LPG conversion caused it because they'd know what's coming next.
However, they will have had to re-route parts of the cooling system to heat the evaporator. It's a possibility that they could have caused uneven coolant flow around the head or insufficient bypass flow during warmup. It's possible they didn't bleed the system properly when it was put back together. In addition, if it's running seriously lean on gas this might have contributed.
Problem is, proving any of the above is going to be a challenge. Head gasket failures are not uncommon on the 4 cylinder engines so it may well just be an unfortunate coincidence that it chose now to fail. :-/
.. assuming it has failed..

By the way gas combustion results with water steam also.. ;)
