What are these? I was told that they were factory Oldsmobile, possible Toranado. They have seven holes for attaching to heads.

I'm going to shoot from the hip and say Cadillac. Just a guess.

My cousin John Foust (Honest John's Caddy Corner) gave them to me and I am pretty sure he knew they were not gas engined Cadillac or he would not have given them to me.
I suspect that they are from a diesel Caddy that used the diesel engine made from a 350 Olds. Funny how both covers have a hole in the side. One looks to be for an EGR valve but the one with the crocked hose is ???

The diesel Olds 350 uses the same valve covers as any other 1964-1990 Olds motor, and these are definitely NOT Olds valve covers. They are not 1960s-70s vintage Caddy (425/472/500) valve covers either. They MIGHT be from a 4.1/4.5/4.9 liter Caddy.

You are right, they fit a '82-'85 4.1 Cadillac. John said his mechanic got the wrong covers for me; the chrome Olds covers are still on the shelf.
