While you are at it it would be a good idea to re plumb the manifold for the thatch modification. The thatch modification is where cooling water is introduced into manifold at it's low end and comes out of the manifold at the high end. This eliminates air pockets and results in more even and through manifold cooling. Search the forum by "thatch modification" to read all about it. There have been many posts on the subject.
Glad to hear you got the over heating problem solved.

So did that gunk end up being engine rust/scale...or mud? It looks like silt to me. That would explain why the acid didnít budge it.

It would be a good ideate take the side plate off to see how much "mud" is in the engine cooling jacket.
