I saw a set of them on eBay early last week. Maybe they’re still there?

i have some factory mopar upper end gasket kits from the 80's , but there not the steel shim type ect....
 
Let me ask a stupid question. What’s the difference between using a steel head gasket and using no head gasket at all (besides the obvious difference in head cc measurements)? I always wondered about this. It’s pretty obvious that steel gaskets don’t compress much, if at all, so why are they used instead of nothing???

When I worked at an antique restoration shop, we got an original Alvis (British car) in to restore. It was a straight 6. Beside having to remove the cam from the rear into the passenger compartment, the motor used no head nor intake/exhaust gaskets. Can't remember about any other gaskets. I guess they depended on really close manufacturing tolerances.

The embossed steel gaskets do seal. The "no gasket" theory won't work. Too much pressure (compression) and a mix of that and coolant and oil.

Oh, so they have an embossed ridge on them? If so, I understand now. The ridge would do a pretty good job of sealing nearly flat surfaces.

Yes. Let me see if I can find a photo.
