First off is that you replace them both and not just one. The intake, and exhaust manifolds must be removed. The heads then need to be removed and checked by a machine shop for warping and cracks. This is a major repair that should only be attempted by someone with the tools and skills to do it correctly. If you have the tools and skill, I suggest you purchase a repair manual for the specs and detailed instructions.

If you are sure that it did not freeze and crack the block, Then the intake manifold gasket is leaking. That is a common problem with the vortec Chevy engines. You need to replace the gasket with a factory Chevy gasket from the dealer.
I'm sorry but i actually have a 99 Malibu and they do have a intake manifold gasket which are commonly mistaken for a head gasket when it blows. Mailbu's 97 to 2000 are bad for them blowing. it is located on top of the engine. it's still very expensive **tamnesha Some Chevy engines of that period didn't have a gasket; just a thin film of sealant.
