Coolant in Oil Pan

Hello Gang! FNG Chiming in for the first time. And do I have a mystery I need help solving.
So my ride is a 1956 F100. The Drive train consists of a Reman 1977 Ford 400(D7TE) with a 77 C-6 Tranny and a 65 Bronco 9 inch rear end.

500 miles ago I threw a couple rods and cracked a head, so I replaced with the Australian 351 heads (no smog crap). Went over the top end with new rods lifters gaskets water pump etc.
A week ago on the hiway (running great at 70 mph) the small gear on my camshaft shredded after I put in a new TSP HEI distributor in it. it lasted about 400 iles and then just ground down to a nub sending gear teeth down thru the crank into the pan. The cam is toast but this bastard needs to be gone through.
I now also have a significant amount of coolant in my oil pan. (about 2 cups) So I pulled out the motor broke it all down to the block.
I can find nothing in the way of a blown head gasket, intake gasket, visual crack anywhere. When the heads came off it all looked clean with no sign of coolant in the piston bores. I have read every thread out there and all I can think of is there must be an internal crack somewhere inside the valleys of the block. Im Baffled. Ill take this thing to the machine shop for magnaflux-ing but I just don't dare put it back together until I find the damn culprit. Help me out!
