Technical Early Hemi Valve Covers - cut as wall hangers?

I guess are cut? no bolt holes, I am not familiar, thinking someonw cut to put on another type of engine for a Hemi look? I am baffled....or made like this?

 

Made to cover flathead. They were cast specifically for flatheads, not modified to fit.

 

Yeah, no good any longer for keeping oil in and dirt out of the top of an engine.

Yeah guessing someone cut to make Hemi look-a-like covers, strange

 

If it has hemi valve covers it must be fast!

 

Looks more like fake Ardun then fake Hemi to me.

 

Purpose built head covers for 59AB. The notch is for the water outlet.
Used to see them occasionally, hardly ever now.
Honest Charley did sell them.

 

Didn't Thickstun make some finned head covers?

 

Thickston did.
Made for flathead powered boats to keep the water off the plugs.
No plug holes like the ones pictured by the OP.

 

Definitely purpose-made Flathead head covers. Here's a set that was on the HAMB for sale a couple years ago.

They are in no way modified Mopar hemi pieces.

 

Or Champion?
