I'll go with the v bands then I only need one for the cross over to be removable the rest already have flanges at the headers and it will be welded solid at the turbo support bracket. I just want the ease of removal because I'm mocking it all up on my 273 then taking it all back apart to clean and paint it to put it back on the 318. I'm sure the 318 isn't going to last long under boost anyway lol so I don't want to have to fight it when I go feeding it shortblocks
