cools the pistons and fills the hydraluic valve lifters  

I'm not certain that that's everything.

Helps cool the valves too.  Sodium-filled exhaust valves work by  
improving heat transfer from the valve head to the guide via the oil.

uch of the 20th Century they didn't always have the money or tools for more

The head gasket is the multi tasking hold out that should have gone dedicat
ed a century ago, even in small vehicle engines.  The oil and coolant ports
 in the head and block could be recast / re 3-D printed to cool anything th
at's being cooled now with dedicated external tubing from the block to head
.  

Then the head gasket could be dedicated to just one task:  sealing the high
 pressure high temperature cylinders.  Not only would this reduce blown H-G
s but when they did blow the engine would still run indefinitely on the rem
aining cylinders.  They may already do this with larger engines, i.e., mari
ne diesels.

First guess:  A multi tasking head gasket saves about 2 minutes labor in th
e manufacture of the engine.
