Did you do a compression check on the other cylinders yet?  I'm wondering if
whatever caused the first exhaust valve to fail has also damaged the others,
or if valve seats/guides/rings/etc. are also in bad enough shape to allow
this blow-by.  My experience is usually that things wear in sets, though not
always.  Curious to hear your result.
