    What is Head Torque for a 150 PSI GPR Head?

    Does having a stock head milled change what the head torque should be?

    Thanks
    TD

    Same as it is for a stock head. 1st 16 ft lbs 2nd 25 ft lbs. Just make sure if the head was decked that the bolts do not bottom out and give a false reading. Somtimes you need to add washers under the head bolts after decking a head.
