In rebuilding the upper end at the Audi dealer, a new head (exchange) costs
$685 at Owasco in Whitby plus $559 labour plus taxes. Add gaskets,
antifreeze, etc. equals about $1,650 CDN. That would include new?? valves,
seals, springs, lifters. Just to put that in perspective, the lifters alone
(at the dealer) are $47 each X 10 equals $470 CDN. plus parts & labour of
about $360 for a total of $950 and you haven't touched the seals, lifters,
etc. If you're into wrenching, you can pickup the parts at about 75% or
less in the States without some of the taxes and without all of the labour.
Your rebuild might include rings, etc and the cost at a dealer as noted
above seems prohibitive when considering how long you'll keep the car.

Either find a recommended non-dealer mechanic or it's Audi mechanics 101.
