Outer Limits 4x4 Board

Hi,
I recently asked about my GQ over heating. Please refer to it on the other page.
My question is :
I have a cracked head on my 4.2 TB Carby. If i replace it.....Is there a chance this will happen again??
Can i put a better head on this engine so this doesn't happen again??
If so, which one.
Someone is sure to have gone through this as GQ are nortorius for this to happen..........What did you do to overcome this. I have already spent more than 2k getting to where i am now. so i only want to spend wisely from now on.
I have replace everything that has to do with the engine cooling.
thanks again.
My Other thread is GQ engine overheating.

i hade head cracking issue's when i turboed mine, I got a brand new head from nissan and PGS fitted it with stainless steel gu headgaskets, No problems yet

Oh and you will be lookin at around 3k fitted

all heads does a bleed off kit which involves 6 lines plumbed into the head and lets prerssure run back into the top radiator hose, i believe its about 500 or 600, i am in the same boat and poo my pants every time the temp guage rises, as i dont want to spend a wad of cash on something i have just replaced
