On my small block stroker Dart, I  had a Real Gasket silicone gasket at the thermostat housing,  never had a problem with it, until I installed the Flowkooler pump.   It blew the gasket out two times in a row.  Then went to an o-ringed thermostat housing,  problem solved.  Just saying that I think that the Flowkooler pump may move more water.  It's what I  will use from here on out.
