Your year and model would help but the basic answer assuming US market
Westy from `86 - `91 is no.  There is not an already inplace piece to
insert headrests for the rear seat of a Westy.  Some people have made their
own but that is about all you can do.  The challenge is making something
that is secure enough to withstand a crash without breaking and causing
more injury.  Someone else may respond with what they have adapted, made,
or a link to more information.  I have seen photo's and a write up that
involved stack headrests and inserts plus some pipe and bracketry but can't
find it at this time.
