<VV> valve seats and "Ping"

[Matt Nall]

 OK, after some reflection, that may be a bit too conservative. I do know, once 
CHT reaches 400F or more, detonation and preignition become a LOT more prevalent 
here. And no doubt, all that knocking will beat on things in a way that not only 
kills power, but engine parts as well, and seats come to mind...

  My exact  beliefs!  When in SoCal I did everything possible to keep from pinging...keep the heads near 300F.


 No that I'm on the Oregon coast I find I can run the 400f for efficiency....  and not rattle!


I've only lost 3 seats in my life.
