[xj-s] Replacing xjs v-12 exhaust manifold gaskets?

In reply to a message from dave french sent Sat 18 Jun 2011:

This is a big-ish job, but not impossible provided you have
the time and undercover space to do it in stages. Roughly,
these are the steps I suggest:

1 Remove induction manifolds. Space is the problem, so I
suggest you remove the HT leads and the cruise control
bellows first of all. Then remove airbox covers and filters;
disconnect and label all the fuel and other hoses joining
the manifolds; leave the injection intact on the manifolds,
just disconnect the harness at the resistor pack on the RHS
wing; disconnect wiring to sensors etc; undo manifold nuts
(24); with a friend lift off the entire manifold/injection
as a unit. All this is explained in Kirbet’s book. Stuff
some rag down the induction holes in the head!

2 You can now see the exhaust manifolds. Take off the
downpipes from the manifolds - you may have to loosen/remove
the downpipe to exhaust pipe joint. So getting safely under
the car is necessary.

3 Unbolt manifolds and change gaskets.

FWIW I think having got this far doing both sides (2
manifolds per side, each does 3 cylinders) is sensible. Plus
you can clean up the V.

Anyone have a good step by step on this. Have a 86 xjsc with 44K
on the clock and one of the head to exhaust manifold gaskets went.
In the shop manual it does not sound difficult but think a pro
might be more time efficient at it. Any ideas.
