If it actually has seat-inserts-it's not very difficult to pull them out and press in new ones. If no inserts - you can either grind (or cut) a new seat if not too bad . . . or have a machine shop cut the head so hardened inserts can be installed. Cast-iron heads are easy. Aluminum heads usually require super-cooling the seats before installing. I use liquid nitrogen since the local cow inseminator always has some available.

As to valve guides - some are inserts and are easy to replace with a press. If not? They can be knurled and resized if not too bad - or - machined for new inserts.
