Thanks everyone for their help. Will post some pictures once I am through with this project. I learned a few tricks that I think would be helpful to the group. I also am a ham radio operator and have restored a lot of tube ham gear (Collins) so wiring and soldering is not foreign to me.

30 mm is correct. Typically 2-3 have to be cut to 15-20 mm to clear the runner and start the thread.

The stock manifold bolts with spacer on 90' show 1 inch or 25mm of thread beyond spacer. The stock manifold bolts show about 5/8 or 16mm of thread beyond manifold flange when installed. Given stock manifold flange is relatively same thickness as header flange a 25mm stage8 bolt would engage head also about 5/8 in (16mm).

LT5 8mm x 1.25 The underhead length is 25 mm or about .98 inches

To clarify - I think once I trim off long, triangular part of the tab, I can put the tab on and clip so the bolt won't turn.

I found out that Stainless Works does do ceramic coating, but it is not listed as an option on their website. Have to call them. Turnaround time for the headers, including coating is 4-5 weeks, so I guess that I know what I am getting for Christmas! Thank for the info, guys.
