I'm on the head gasket side of the discussion. The only persuasive answer so far. Down hill running even wide open usually causes the governor to close the throttle plate (at least part of the way) to attempt to reduce engine speed. This actually cuts back on the amount of compressable mixture in the cylinders, a high vacuum,(unlike a diesel). The rumbling and popping in the exhaust is due to the fact that there is so little mixture in the cylinders that it often fails to burn till it gets into the hot exhaust system. Where it ignites with a report. I do not think it would over pressure a head gasket, but it will blow the sides out of a weak muffler. A careful flatness check, and possibly a cleanup surfacing and a new gasket are the ticket. Just my 500$ estimate. JimN
