yea you can feel a groove. i just read an article in a mustang magazine about loc-wire and this looks like it how they describe it, but someone told me its not a loc wire

It does not look like a lock wire to me. I have these gaskets on my engine. The groove will be consistant and milled into the head. It will circle each chamber and be very noticeable.

All head gaskets have a fire ring around the chamber and will leave marks like you are pointing at in the pic.

it does circle each chamber and is noticeable, its harder to see in a picture then in person. im tkaing the heads to a mustang shop by my house to be looked at.

Does the groove appear to be machined into the head about a 1/16th of inch deep and wide?

mcfomco

You need to remember aluminum is softer that cast iron and the fire ring will leave and indention in the head a little when torqued down. Thus giving you the impression it has had a loc wire gasket installed.


The first picture i can see the groove is not uniform around the chamber. It also appears not to be machined into the head.
