    Default compression question

    Is it possible to change a evo 9 headgasket to a evo 8 gasket? And how much will the compression change?

    I found this info, evo 8 gasket: 0.026", evo 9 gasket: 0.041"
    Is this correct?

    Yes, the EVO8 gasket is thinner it also has two extra water ports on it.
