I read the article finely...
It looks like they adapted race motor machining tricks to the production line.
Installing the mains and installing a torque plate with head gaskets in place of the cylinder head has been done for decades.
Heating the block for machinging is newer.
I have read that very well machined block will allow for the use of lower tension rings all around.
Now they machine the bare cool block and hope that torque and heat deform it to the correct shape.
