As an example, my 63 Lark convertible, six and automatic. If there was ever an engine that had to work hard for a living, its this poor little thing hauling that heavy convertible around. 93K miles with no end in sight. Has been from MD to CO and back and keeps up with traffic in the Baltimore area. Head does not seem to have ever been off, and certainly not in the last 40K I have driven it.
Not trying to be too argumentative, but if you haven't removed the head for inspection, how do you know you don't have exhaust valve seat recession?
On my 55 Pat, prior to hardened valve seat fix, the engine was still running smoothly and a compression test was OK (not really up to spec, but acceptable). But, it turned out the exhaust valve seats were pounded down over 0.100IN and the exhaust valve face edges were razor thin. The only clue was that the exhaust note sounded "flat", not healthy. I don't know how long it would have gone before one of those exhaust valve edges broke off dropping nasty metal parts down into the cylinder.
