metal head gaskets vs fiber ones

Ordered a new Overhaul gasket set from Davenport Tractor. Surprised when I opened it to find the head gasket is a dark colored fiber type gasket. I need to study it carefully but wondered what your thoughts are. This is for an unstyled G Deere.
 
Did a rebuild on a 560 Cockshutt with a Perkins L4 diesel. Got a victor reinz gasket set that included a fiber head gasket. Long story short engine overheated and put a valve through the top of a piston and messed things up pretty good.

Not completely blaming the head gasket but...
my understanding is

copper gaskets have different crush when torqued
copper gaskets also distribute heat more evenly.
My oppinion: Use oem head gasket!
 
Thanks. I was afraid of that. I will suggest to them that they try to get the copper gaskets. Luckily I found one but it increases the cost of course if you buy a gasket set with wrong head gasket and then turn around and buy the correct gasket.
 
For most common old-time applications, what you are calling "copper" head gaskets had a layer of asbestos between two copper layers.

Even before asbestos was removed from most products, steel was used top and bottom, and copper phased out in most cases.

Often both metal and composite styles were available for a given engine, and both (IMHO) did the job equally well when installed properly, with the surfaces clean, and with proper torque.

I find it far-fetched to blame a composite head gasket for an engine self-destructing ASSUMING it was the proper part, from a mainstream Co. (Victor or Fel-Pro), and properly installed.

As far as copper, and heat transfer, a Shutt would be a low HP density water-cooled engine, and I wouldn't think the head gasket should have a lot of "heat transferring" to do???

Unless the engine was run out of water/overheated.
 
They don't want to spend the money to get the good gasket. If you plow or pull this gasket is junk. I think I sent you the only source for the old style, GOOD Gasket. Was the gasket still $150.00 ?
