jack 3.2 v6 engine failure.

Hi,
This is my first crack at this forum so be gentle with me please.
I am a avid 4wd enthusist that is new to the game, just last year i purchused my first 4wd being a 94 3.2l v6 jackaroo. We were going out bush every chance we get and have finally found something the whole family can enjoy. There is not a day go's by that my 3 year old son ask's when are we going bush again. All was going well until the cam belt broke and destroyed about 15 of the 24 valves in the heads. I havent as yet pulled the heads of the block but are hoping the bottom end is still ok. My problem is that im looking for some new heads or maybe a complete motor. Just to make it more difficult is that i lost my job and are a little cash strapped. (Julias pay doesnt lend much to engine rebuilds). I not asking for charity but some cheap bits that are sitting around someones shed they want to get rid of. Im in the Ballarat area and are willing to travel to melb and suburbs or work something out for futher distances.
Please help me to get the family out (and please a little boy) in this great wide country of ours.
Thanks for reading.
