If your burning oil in high rpms its going to be your piston rings
If it's the valve seals, it's not cheaper to rebuild the whole motor...If you replaced the spark plug seals and valve cover gasket- try the cam seals.
Most likely your rings or valve stems need replacing. At which point it's cheaper to buy another motor and rebuild the new motor on your spare time. Once the motor is rebuilt you can swap the motors EASILY in a weekend.
