That's great news Bruce!
We have a process over here called redistrip. 
They have 3 separate processes. 
Cast iron - It's awesome for blocks and heads. Removed everything that isn't cast iron. No crap left. Only cast iron. 
They also have a process for aluminum. 
Only leaves aluminum - they did my shrouds. 
And one for steel. They did my guards/ bonnet etc. no paint, no bog, no filler. 
Their cast iron process has no equal. 
Glad you caught the issue before it cost you an engine. 
You now have 2 options in my book. 
Paint the oil side inside the block with red lead primer like the factory did. That's what I did, also inside my gearbox. 
Or get the block epoxy vacuum injected. 
Epoxy vacuum injection is what most manufacturers do to high pressure alloy castings. 
Basically, they put your totally cleaned block or head or whatever into a vacuum tank, then put in a bath of 2 pack epoxy, evacuate all air, and the 2 pack is sucked into every microscopic air hole. 
Never leaks. 
Google the processes.

They pressurized the oil gallery to 70 PSI and it help pressure; nothing bleed into the water jacket.  Rather, the shop cooked out a bag full of sludge from the water jacket in the back of the block.  Apparently, the regular hot tank dipping before didn’t dislodge all this gunk, and the circulating coolant would dissolve just enough to foul the coolant with the oily mess that sure looked like fresh motor oil mixing with the coolant.  Fooled me, for sure.  For good measure, we will coat the water jacket with some epoxy, then rebuild the motor with Denis Welch pistons, street cam, bucket lifters, hollow push rods and fly wheel.  I am excited to experience how it will run with the new DW parts to go with my DW oil pump I installed years ago.

> Finally diving in to diagnose and fix the oil in the coolant. Hoping it's just the head gasket, but since it started after the engine was done 11 years ago, I am suspicious that it's the oil gallery-water jacket wall between number 4 and 5 cylinders seeping high pressure oil into the coolant. Has anyone actually had or known anyone with this problem?
