From your description on the block issues, the "diarhea" coolant etc... sounds like it could be a big part of your problem.

I,ll second that...With all the improvements you,ve done to your cooling system and still having issues.I,d say the block needs to be hot tanked to get rid of any crud/blockage.Who knows what was used/dumped in it before you got it?JMO
