Does any one know some contacts lenses that have the diameter 14.2 and base curve 8.6...

Eyes have to be measured for contact lenses and made to fit. No one is going to give you this information.

BC values are a bit like clothes sizes - just because you are a BC 8.6 in one brand doesn't mean you will be in another.

Do you wear spherical or toric lenses?

Actually many brands have that specific fit for lenses, and if they don't they can be specifically made. This needs to be discussed with your eye doctor to get the best lens for you and then discuss the fit.
