The first step was to replace the damaged guides.
The two from the damaged cylinder, and the intake next to it had been removed.

These heads use guides with an odd sized OD, and I think the previous shop pulled the one to see what size it was.
At this point, I hadn't really looked at the rest of the head too closely, and just took 3 larger OD guides I had here, and turned them down to fit the hole in the head.
After that was done, and they were sized, I got to the business of installing the seats.....
