Replace the cylinder head gaskets, but have the heads checked for cracks and flatness. There is a spec for the allowable amount of warpage before a head must be resurfaced. That is commonly around.002" to.005". If you plan on doing this yourself, proper surface finish is critical for the gasket to bite into the surfaces and seal. Do not just slap in a pair of gaskets and expect that is all it takes.
