SOURCE: head gasket blown
there are many was a head gasket can blow . sometimes they just leak to the outside sometimes they leak to the coolant and then it blows out your antifreeze. if you have a blown head gasket you will see it when you pull the head. and yes you should hace the head checked at a machine shop and install with a new head set never reuse a gasket .

The conventional wisdom is that this is a possibility with high mileage engines. But the option of just rebuilding the head versus the entire engine would make the choice easy for me -- I'd rebuild the head... I would say the probability that a new head would damage the engine is kinda low.

I would change both, as well as use new head bolts. Make sure your heads are not warped or cracked, especially the one that is leaking. There may not be any need to change the head if it is not cracked. These are prone to blowing a gasket especially after 150K miles or so. It will not cost a huge additional amount to change both head gaskets since the engine will have to be disassembled down to the heads anyway. Hope this helps you, Rick

Get a Chilton's book on the car. It will take you thru the whole job, and give you the torque specs for putting it back together. You will need a torque wrench, foot pounds, and a good socket set.
