[Healeys] Intake Nuts

[rjhco]

A while back, one of the listers suggested replacing the intake manifold
nuts with a special aircraft nut that is undersized so that it is easier to
fit a wrench in the tight space.  I cannot locate that posting in the
archives.  Anyone remember what that type of undersized nut is called?  I
think they may be fabricated from Titanium as well.
