Personally I'd do a compression test and a leak down test on each of the cylinders. This will give an idea of wear generally and hopefully where the main problem is.
Then you can strip down that bank and change the head gasket if general wear is not too bad - it might just be an HG failure.
There are lots of things you'll be wanting to do if you get the engine out, strip it down and want to rebuild it but in the shorter term I'd do the above. You'll also know whether you've got any major problems that might mean the cost of a rebuild is going to be prohibitive.

Not sure how much top hat liners cost??
