Just curious.  Is this an engine that sits a lot, with a long time since last disassembly and boiling?  Wouldn't engines with corrosion in the water channels may need additional coaxing to cool enough? 


Like Randall, I run a stock water pump and don't have problems with overheating during the hottest days of summer (it can get 90's even in NH).
