Pedestals do not need to be machined for the 505 cam.
Valley Head service is still in business as far as I know. They were once a hot spot for performance head work. Ask for the "old man", I forget his name. He knew the Cleveland heads. He'll be quite old if he's even still around. Happens to all of us. Even if the old man isn't around, they should be able to do the basic work.
There's a guy in Valencia that builds Ford race engines. I can't think of his name at the moment either. He's not a Cleveland expert mind you. If it were me I might be tempted to crate-up the engine and ship it to Jim Kuntz.
