The burnt valve symptoms were the obvious "missing", especially under
load.  Finding out about the burnt injector tip was initially noticed
when removing the injector prior to removing the head.  At first I
thought it may have been the injector, but a compression test verified
that the exhaust valve was burnt.

Burnt injector tips can cause one of two things - slight misses
throughout the power band OR the exhaust to run rich in that one (or
more) cylinders IMHO.
