[xj-s] Tell me what you know about "Pinned Valve Seats" on an 89 XJS

my 1989 XJS dropped a Valve Seat several years ago. A while back,
someone mentioned ‘‘Pinned Valve Seats’’. Well, I kicked myself for
not knowing about these when my work was done. Last week I was
looking through my Tickets on the XJS. The ticket was there for the
XJS head work. Pins were listed on it. I called the Shop &
mentioned ‘‘Pins’’. The guy said immediately that I must have a 12
Cylinder Jaguar. His opinion was that a 12 cylinder Jag could drop
a valve seat without being run extremely hot & mine had not. He
told me that anything could happen, but it was unlikely to drop
another one if I used reasonable driving care. I assumed that
meant, don’t run it red hot or other careless things. So, I do
have ‘‘Pinned Vale Seats’’. What is your opinion on this? I would
like to know a little more. Thanks, Ron–
