Coolant Pooling in Intake Manifold - 230 Flathead 6

[rtferguson39]

So I ran a leak-down test, and found some crossover from cylinder 3 to cylinder 4...imagine that. I pulled the head and this is what I found, block side of head gasket pictured below. To me, it also looks like this gasket was allowing coolant to pass from the center cooling passage (right in picture) into cylinder 4. Anybody else have an opinion on this? 

An initial quick cleaning did not shoe any major cracks in the head. I will be doing a more thorough inspection this evening of both the head, and the block, again.
