A lot of times NOS is the way to go for engine parts. Usually. Is there any reason generally that this wouldn't be the case with even a gasket set? There aren't any shelf life issues with gaskets are there?? I don't hardly trust any of the &@!! being put out there today, basically.
NOS may not always be the way to go. Hard to say this many years down the line if the product is up to the standards it was supposed have so long ago.
I found a brand new pair of wing windows for my wagon. Everything from top to bottom. Outer frames, framed windows with genuine Ford glass, weatherstripping, handles, springs, everything. Complete, assembled, in the box Ford products. Take out the old units put in the new, done. They looked perfect and worked great. ($$$)
In less than six months the plastic between the layers of glass had begun to show considerable white stuff around the edges the same as old glass often does. Within another year or so the glass looked about as bad as what I had replaced. Maybe worse. Bubbles creeping in on both up to an inch from the edges in places, at least some everywhere else. Discoloration through the whole pane on both. Stainless and weather strip look great. The glass is as bad or worse as any on the rest of the car. Only one window on the car doesn't have the original Ford logo etching on it. (Clear but wouldn't you know it's cracked.)
Have to figure that though exposure to the sunshine had something to with it, the age of the glass was the most important thing. It began failing immediately after taken out of storage. Only did what old glass does. Had to do it real fast to make up for lost time and it caught up with the old glass real quick. Because it WAS the same old glass.
Was totally unexpected by me and several other oldtimers that watched it happen. Made me start thinking twice about NOS stuff. Electrical certainly. Fibrous products as well may be suspect. Some level or another everything might be suspicious
Is it good or isn't it? Good question. Think about it in a box, or not, in a drawer or on a shelf, or not, in an un-climate controlled storage area of some sort in some part of the country or another for 50-60-70 years. Don't have the answer myself. Got one good lesson on the subject. Now I can't say.
