BTW: I've loked at some pictures of the engine gasket kists. Out of curiousity mostly. Are you saying all the gaskets show are steel lived with Viton? Or should be to meet OE specifications? If so, I'll have to keep that in mind if I ever buy a rebuild kit.

The head gasket is 3ply stainless with Viton around each seal edge. The water pump and thermostat which do not contact any fuel but still are stainless with Viton on the edges. The exhaust gasket stamped stainless. Most other metal surfaces are sealed with a carbonized silicon sealant which also would not react to the E85. Almost every o-rings used in the engine is Viton. They have to be so the synthetic oils do not affect them.
I don't recommend using E85 but it because the octane rating can be 100 to 105. Higher octane means a hotter faster burn. This change ignitions time in relation to engine timing that the engine is not tune for. That increase the possibility of burning a valve or seat.
