Dart 360 heads, I do not see how a 4.56 gasket would work. I think it would protrude into the cylinder the way it locates.

Now the two below are available will ship today. BTW, the gasket measured just a touch over .040. Can I use either of these?

We are in the middle of a refresh and my pistons are 4.565. The gasket that were on there before with no problems and the new ones going back on are the Fel-pro 1075.
