Blown head gasket petrol 4.5L

[Bogger]

Hey,
I've just blown my head gasket at 260000kms on my petrol 80 series and was wondering what my options are within a small budget.
My ideal option would be to drop a diesel into it, but I'm wondering which Diesel engine would be the cheapest to put in?
Or should I just fix the head gasket?
Or should I just put a new petrol engine in it?
Putting an ls2 definitely isn't in the budget either!
Also if anyone in Australia has had this experience what type of cash am I looking at for someone to do all these?
Thanks a lot

Pull the head and fix the gasket. Make sure you have a machine shop measure to see how warped the head is.

And make sure your cooling system is completely up to snuff.
