Many good ideas here. When I get home next week, I'll tackle these headers in earnest. I'm sure I'll be using a few of these suggested techniques. I think some modified tools will work in some holes, special or modified bolts will work in some holes, and maybe some dimpling of the header will work for some holes. I'm still nervous that dimpling may ruin the ceramic coating though. I'll start small on that process and see how it goes.

Once the headers are finally on, and the RTV has set up a day or two, it's the much anticipated first start next. Getting close, Fingers crossed.
