I'll drive it someday
I'm about to pull apart my heads for inspection after my minor engine mishap.
Bird and others questioned my use of Teflon positive stop seals on a street engine because of the potential for excessive wear on the valve stems. Since I'll wreck these pulling the heads apart, this will be a good time to replace these if there is a better choice of material. These are essentially what I used:

For a lower mile, infrequently used, heavily driven motor, is there a better long term material than Teflon for an iron headed, moderate compresion 427 small block? Viton perhaps?
Opinions welcomed.
