[T3] No. 2 Exhaust Valve Problem

[John Jaranson <jaransonT3@comcast.net>]

OK, I am looking for some advice from the experts out there.  As I mentioned
the other day, the exhaust valve on Number 2 cylinder was tightening up.  I
pulled the head today and the #2 exhaust valve is clearly more recessed in
its seat than #1.  It is not real obvious in the picture, but have a look.

What are my options?  Can I get a new seat and install it?  Should I just
get a new head?  How long can I run on this head the way it is?  (The valve
tightened up in 800 miles or so)  What can I expect as a failure mode, if I
don't do anything right now?  Am I likely to do damage to parts beyond the
head when it fails?

I also included a shot of the #2 Piston top.

It also looks like I may have been getting a little blow-by between the
cylinder and the head.

Any and all advice appreciated.
