    Is the block surface true? I also wonder if the bolt holes are clean and threads undamaged. Maybe the bolts are bottoming. This could also be a problem if bolts are different lengths and are in the wrong holes.

    I had the head milled, and correct bolts are now torquing to spec, had to heli coil holes, im guessing its the block but not worth machining. Time for a motor
