How do you know you get a good seal at the exhaust port?
The only way to really know is to take down the heaterbox and look for soot on the copper gaskets. But by then you will need to anneal the gasket again and hope that you get a good seal the next time you mount the heater box too.... Tips and tricks are most welcome.... |

I've taken to using McMark's feather technique. Pressurize your exhaust system using the output from a shop vac and probe about the head ports with a feather. It's surprisingly accurate at locating even the smallest leaks. Plus there's the bonus of not working on and around hot heat exchangers. I recommend trying it.
