I am having trouble finding out what the correct material I should be using in the cylinder head o-rings.Does anyone know what I should be using?I tried using polaris storm o-rings from the dealer but they are too thin to work.

yea. I'm that stupid.
The motor is custom built using cast liners bored out to 72.5 mm .
all I was asking was what material to use. Viton or other wise
