I am wanting to do a stroker rebuild on my Z (as I am convinced my crank is on it's last legs) and I have read many times that the best option for this build is to run Ron Hamp Cams and Eddie's stage 2 valve kit. I believe without this combo people run into issues with head gaskets blowing out.... Unfortunately Eddie will not supply this gear on international order due to shipping/insurance issues. Being that he is the only supplier for RHC I am left with a small dilemma and am seriously contemplating selling the bike and moving on to bigger better wheels. Can anyone out there recommend another option for quality cams that suit a +4mm Hot Rods stroker crank rebuild ?
