Sorry, that's not my level of expertise. My studs looked OK but I found the fasteners to be very loose. They only get 15 ft-lbs of torque to tighten which isn't much. I suspect you may have a problem with stainless in the aluminum heads, maybe someone else will comment.
The shop manual didn't call for any anti-seize of the like so I didn't apply anything to the fasteners.
