Well, yesterday I was ready to fire up my Interceptor III for the first time in over a year. Filled the radiator with coolant and whilst under the car double checking things I noticed that there's coolant leaking between the heads and the block - quite significantly. The heads are torqued down to the correct settings, head gasket is new as well.

I know I'll have to pull the heads back off but can anyone suggest on what else to look for?

Is it definitly coming from the head / block joint? Anything else which could be leaking eg core plugs. Why did you need to fill it - had it been empty / low when you last used it?

Dont be too hasty I would double check its coming from that location for certain and not weeping down from a failed valley gasket/water housing/w-pump for example or similar joint frown of course you may of nicked the head-gasket on cyl head replacment if your using head bolts rather than studs , those heavy heads not the easiest things to locate whilst motor in situ scratchchin
