Follow up question - how do I figure out if the 
seats have been ground too many times?


======================================


1  When the valve top  is level with the head material!


2  When you have a good spring..and it takes 0.090"  ship to get seat pressure to spec!


But... anything that seals can be used..


  I've seen  engines that won't rev over 3 grand... shim the springs and whola!
