    WTB 650sx High compression head

    Hello guys looking for a 180psi head for a 650sx . I have a Mariner head that keeps blowing head gaskets like a fat kid eating cake.

    Is the head warped? I have always had good luck with Mariner heads. If the head isn't
    warped, your cylinder may need to be decked.....if that's the case, a different head may
    not fix the problem.
    2001 Superjet; R&D, Blowsion, UMI, Riva, Wetwolf, Ocean Pro.

    1987 650sx: Mariner, UMI, Neo Designes, R&D, Jetsports, Renthal, Hydro-Turf, Skat-Trak, Reworked stock pipe, 40mm carb, Wetwolf F/S cone.

    1986 JS300; lots of mods, fast for a 300...I think

    1987 X2: Rips pretty good and has some 80's flare.
