I need to replace the head gasket on the driver side of my 1999 4.6L Romeo engine. I have a few questions regarding head gaskets.

Does anybody have any opinions on which would be better: MLS or Composite?

Anybody used the composite gaskets and have negative experience with them?

It sounds like the composite gasket might make sealing the cylinder head easier since it is not as particular about tolerances and surface finish but I am not sure how it would hold up over time since the head is aluminum and the block is iron (rate of expansion/contraction differences.)

Thanks,
Eric
