Update. Bought 3/8 and 1/2 in t50 sockets from snap on. Dealer threw in a spare bit as they both use the same one. Got 5/8 (grand total of 8/12) out. One is rounded very badly (inside). 14mm bolt extractors won’t bite on the OD. Going to try to weld a piece of 8mm Allen key about 1” long into the rounded one tomorrow. Will have to drop the valve down into the cyl to get enough access. If that doesn’t work, I’ll see if the Machine shop can cut the heads off and get the head off that way. I’ve never seen this much flex in a bolt in my life. Any additional ideas would be welcome.

Dllrd23, Do you have enough room to get a Dremel around the head?

Yes. If I let the valve drop into the cyl I will have about 189 degrees open the other side is close to the wall of the cyl head. I’ll post a pic shortly

Time to break out some good penetrant chemicals & soak overnite.
