I'm not sure where the cavity goes either. but there is a divider plate between the water pump and the timing cover, so the area there is sealed from the pump and should be dry. so as long as the cavity goes nowhere i should be good....at least that is what I am hoping.
I've seen stuff just like this in oil galleries on 302s and 351Ws, but not on a 460 in what looks like a water jacket. You need to post this in the 385-series forum and ask if anyone who has rebuilt a 460 has seen this before.
I have had a bunch of them do that, I fixed one that was not bad with a plate and jb weld, but had a few others that I had to replace. Not sure if it would hurt anything, but it's not supposed to be like that, so I wanted it done right.
Since your already into it that far & you know how hard it was for you to get to that point at the front of the engine, if you patch it & the patch dont hold, its doing the same amount of work all over again to go back in a fix it or replace it.
Dont know if they are worth a crap or not, but some new ones on e bay for 44 bucks, w/ pump block off, gaskets, two bolts & dip stick plug.

I have rebuilt my 460 in my truck, had a hole in the cover in about that same spot. I did jb weld, but after I looked it over, I discovered that it is an empty cavity, its fine. You can JB it if you want to, but its not nessicary. It doesn't connect to any oil passages.
