Questions about a 2006 5.7

Getting exhausting. Got these supposedly 70K mile eagle heads, finally have the short block back together so moving to the heads. Decided to pull the valves to check the seats, clean the valves and lapp since I dont know how these were sitting, like open valves after someone bought the intake and since we got seals with the kit, change the seals.
Everything is fine until pulling the last exhaust valve which is carboned up so bad it actually beat the guide up about a half inch into its bore. This of course smashed the rubber of the valve seal. So the exhaust port is caked with oil, only wet one of the bunch.

What are the options? Knock it down, pop it out so it can be frozen with a heated head and put it in right, or do these need to be machined out and replaced? I figure if I just heat the head I am also heating the guide so its not going to make it easier to move.
