I used Auto-RX on my engine and had a very pleasant experience. It was not as bad as yours but it cleaned it of all the varnish and anything else that was visible under the valve cover and now everything is bright and shiny.
Auto-RX is a gentle cleaner that liquifies sludge and varnish over a 1500 mile period and then drained. A 2000 mile run of non-synthetic motor oil flushes the liquified contaminants away. If yours is as bad as you say I think an oil filter change at 1000 miles would be a good idea, too.
The website for further information is www.auto-rx.com . The Reader's Digest version is that ARX is made of lanolin esters that liquify the sludge like Dawn dishsoap straight up does to a greasy pair of hands, then the liquified sludge is rinsed away by the clean oil.
Again, it's a gentle operation over several thousand miles so you don't have to worry about big chunks breaking off and clogging anything up.
That, plus a switch to 5w-20, or at least a very thin 30w like Havoline Deposit Shield 5w-30, ought to do the trick. Wouldn't hurt to shorten your intervals to 4 or 5k miles after the ARX for the duration of the sludge removal.

Thanks for all the advice, folks. We'll probably take Ken's suggestion since that seems to be consistent with what I've elsewhere, oil change, Sea Foam, etc. I'll let you know after the second oil change.

I don't know what makes Sea Foam tick, but it's almost as good as moonshine...

Here's what happened...
We ran some Sea Foam through the gas and through the crankcase, but nothing has stopped the noises. We've had numerous oil changes, but that hasn't help either. The last garage told us that the noise is from the timing chains slapping on the housing and that they could replace them, but they'd basically have to tear down the engine. They tried to sell us a new engine because the current one is so gunked up. They suggested running BG Flush through it, so we said do it, but they changed their minds saying that it could blow the engine if the gunk clogged the oil pump, which would essentially require replacing the engine.
We're still at square one with the noises in the engine. Now we've had to replace the transmission because it wouldn't shift. The mechanic said it had self-destructed and bits of metal welded themselves to the inside of the transmission itself. This X is getting expensive.

You can get a Ford reman 2V V10 and installation at a Ford dealership for around $4300.
Also I hope your transmission cooler was replaced or at least flushed real good before they installed the rebuilt tranny. The cooler will hold metal shavings, dirt and etc that will kill your new tranny.

It could well be the timing chains slapping - maybe the tensioner has gone bad, or the guides themselves are so grooved (and the chain is so stretched) that it can't take up any more slack.
Does it make this noise at idle?

I agree, probbably the chains, could be from bad parts or lack of maintiance.
I've had excellent luck running a qt of ATF in my (and all my Ford fleet trucks) oil to help clean it out. My 99 V10 had 180K when I bought it this fall and after 6k and one oil change with 2qts of ATF in with FORD 5-30W, no crap and no valvetrain noise! My engine was full of gunk too. The oil turned black within 100 miles of driving after my 1st change. Now after teh 2nd it's gone 3500 and is still honey colored.
I can't imagine why someone would want to go 7500, let alone 10k on Penzoil! Hopfully it didn't have a FRAM filter too!
Good luck, looks like you're in for some $ or a new ride.
