Milling for compression

I know nothing about the /6 but I am a machinist....If you mill .1 off the block and .1 off the head you would then remove .2 off the threads of the head bolts, clean last thread and deburr completely. The questions is: Will there still be enough threaded portion left on the head bolt so that the shank does not bottom out into the block?? Most head bolts have some extra threads beyond what is needed to properly torque (there is a reason for the extra threads), if you are familiar with "thread theory" you'll know that you need a certain number of threads beyond those in the block to prevent premature failure.
