Backplate should not be a problem, but the Greenhead's I have have a head gasket on them that from memory gets wrecked when the head comes off.
That's why I have never taken a head off any of them.
If you still feel you must pull it all apart, just put it into you cooking oven at home on a metal tray on a high heat.
Using gloves the liner should just pull out I guess.
Good luck.
