Bright metal plated acorn cylinder head nuts were not standard or optional on your car. However they were still available as service parts for those prewar senior cars that had them or offered them so any dealer or person could order and install them.

No need to remove the intake/exhaust manifold assembly to remove the cylinder head. If you're going to do a valve grind, having the manifolds removed makes it a bit more convenient but still not necessary. One trick that's sometimes helpful to break the adhesion of the head to the gasket and block is to remove all the head bolts and washers if used but leave the spark plugs in place, and hit the starter motor; sometimes the piston compression will "pop" the head loose.
