    Will these heads raise compression out of the 93 octane range?

    I am not 100% sure. Give skiworx a call and Steve will be able to give you the answer to that. http://skiworx.com/

    These will put you at about 165 -170 psi 108 octane or 110 leaded will be needed.

    Can you take the one out of the package and turn it over so I can see the bottom and see if it's a gasket or oring

    Its an o-ring. Didn't know there were differences. Is one better than the other?
