Must have a cracked block because it sounds like you went through the cylinder heads completely and if oil is still entering the crankcase must be a hairline crack that is leaking

There aren't any freeze plugs behind the timing cover on the SB Chevy engine. Did you check the head surface to ensure it is flat? If there is any warping from overheating, the gaskests will not compress correctly and a leak will develop and it doesn't take much warping... A cracked intake manifold too can allow a coolant leak into the lifter valley. Or as another poster says, it may be a cracked block.

BTW: Running an engine with anti-freeze in the oil can cause severe bearing damage in a very short period of time. Don't run it like this.
