The exhaust valves are sodium filled. Good luck melting one of those. A garage in ga with extensive m96 data who actually shares his data (NOT RABY) found the only valve related issues on the 2.7 and 3.2s to be related to lifter springs. Navarro mentions that on his website as well.

I guess I'm a bit confused though...How do you know what your valves look like if you have pulled your head yet? |
Thanks for the great explanation on lean versus rich in these cars. Very helpful!
I have pulled off the exhaust manifold and the intake manifold and I can look down in the ports and see that both of the intake valves are broken off and one of the exhaust valves is broken off. I found bent pieces of intake valve stem in the intake, but looking in the exhaust port the exhaust valve stem is in perfect shape other than missing the head.
Whatever happened it was isolated the cylinder number two, I don’t see any of the same problems on 1 or 3 leading me to believe it it was not a valve train issue.
The intake gasket looked relatively normal, but looking at the head it doesn’t look like it was sealing properly. Thus my theory that the intake was warped. I’ll post a picture of the gasket later.
