Begs the question: How did the 'bag full of sludge' get into the      water jacket?

So, the machine shop has gone through            my block and low and behold, oil is not seeping from the            transverse oil gallery into the water jacket.  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?
