To remove the seat get an old valve that will fit inside the seat on the existing valve. MIG weld it to the seat and before it cools hammer the vavle
steam where it goes through the valve guide to remove the seat.
This is the only way you can remove the seat BUT it damages the seat so you have to fit new ones.

To not damage the seat? Cut the head away around it 
Sorry, couldn't resist.....
As Dave said, you will damage them to remove them.

Valve Guides
My old man is filing 8 thou from the inlet valve guides so I can shim and press the valve guide in nice and tight. Have had to use quality shim
material from a marmalade tin, gold medal marmalade. Should know by tomorrow if it will work after grinding the valve seats.
