ANYONE having TROUBLE with TEFLON valve seals.

[TOOOFST]

We have Issacs GTS with a few leaking seals.They only have a couple thousand miles on the new heads/cam package.Think we'll go back to the old rubber!
What are you using that worked for several thousand miles or so?

This is common with teflon seals. Try using viton seals if you have changed valve springs or rubber with the stock springs.
