[urq] 83 Urq Head and EM change questions

[David Ritter]

Greetings,
My search last year yielded a rebuilt wx head and a good exhaust manifold.
So, now that winter seems to have relaxed it's grip, I'm thinking ahead
toward finally getting this done. The car is still stock CIS, K26 oil
cooled turbo.
The questions I have are about the remaining parts needed to do the job.
I have a partial list going and would appreciate input from those who have
done this before.
Valve cover gasket, head gasket, and head bolts I assume will have to come
from Audi. I don't have a dealer within a 3 hour drive, so I am also
looking for mail order friendly Audi dealers.
Do intake and exhaust manifold studs and nuts come only from Audi dealers?
Water pump, timing belt, and gaskets should be available from independents
I would think. What is the "good" water pump brand or brands these days?
What other parts am I forgetting about?
Vendor suggestions appreciated.
Thanks,
Dave
