Conventional wisdom is that on the Corvair you DON'T want to remove the head studs at all, unless absolutely necessary. This is because supposedly the threads were formed in part by the special stud ends during the manufacturing process, and once removed, that connection will be compromised. I did exactly what you did on my first engine, and in the eyes of many, trashed my case on the spot. I still have not used that case, but folks are now using some of the incredible new Loctite products (620, I'm thinking, but that's off the top of my head) to stick one or two "loose" studs back in, so I guess it's not a stretch to think you could do that with all of them. There's an entire email list devoted to the CorvAircraft engine, run by the same guy that runs this one (me). Just send a message to corvaircraft-j...@mylist.net to sign up. If that doesn't work (although I don't know why it wouldn't, but sometimes it doesn't) email me direct. You'll find a lot more expertise on the subject there than you will on KRnet. Welcome aboard on both counts, however.
