using a flat round punch chisel...
but,....the funny part.
the cylinder head can Not be heat,
MUST BE laying flat in a flat surface so, at the moment You knock on the valve stem the head WILL NOT BEND and will be straight at the moment of installing
before installing check the internal measurement in the bronze valve guide for accuracy and tolerance .just to be sure the new one won't brake.
P.S. when inserting the new valve in the old valve guide check how much lateral play you have.
