I know Lyc recommends 2" from the flange, but that seems to be for accurate
temps.  Isn't what you're looking for an indication to lean by?  in that case,
wouldn't it be OK to mount it in the pipe that exits the iron manifold?  Your
temps would be lower, but peak is peak, and I would guess that's all you're
looking for.
