I'm in the middle of a 7MGE rebuild (you can check out my thread on this form) and have learned not Head gaskets are alike. The factory gasket that lasted 20 years had copper crush rings around all the water ports. I purchased a complete engine rebuild kit from the shop for $200 and the head gasket did not have the same crush rings as the OEM
So I checked out the gaskets from CAR Quest and NAPA and they all have the same OEM crush rings at $85 for just the gasket. I am going to toss the one from the kit and pay the extra $85 since I don't want to do this job for another 20 years.
