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 .

if you get a haynes repair manual and follow it step by step everything should go fine. or clintons. if you have questions about what its telling you to do then that would be a good thing to ask. the problem is there are alot of different designs for engines and it could be affected and it could not be. but if your not sure you definitly need a repair manual. it would tell you everything but it will guide you in the right direction

SOURCE: blown head gasket
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
