<div>I'm in the midst of this too -- my plan (unless I am talked out of it) is to use the Ultra Copper Goo from Permatex on the pan letting it set whilst upside down on a perfectly flat surface. Then use Hylomar between the gasket and the block.</div>

<div>If the copper stuff proves to be a bugger to remove at least I'll be working on the pan & on the bench, not under the car looking up.</div>
