So once the head thickness gets to 138.68 mil then its rubish and only good for the bin
Is this the same for all heads 2wd & 4x4 ?

mine is 137.8mm. there is no reason to bin the head. the only concern is the potential for valve to piston contact. lop some off the piston crown or get lowerc r pistons
