^no problem that's what tech is here for,that's how I kindda knew what was wrong with your studs most people take the head right off and oil and coolent fall to the holes and when people try puttinf bolts or studs it will not go down all the way..so when people bring mea block to build 1st thing I do is check the walls then 2nd is the bolt holes for that problem or stripped threads..good luck with your build
