Change in plans. Another new build begins

I hate to say this but some of you guys try to over think engine building. Don’t make it harder than it is. I had an engineer tell me I was wrong for telling a guy on Moparts in search of water pump bolts to just figure out the lengths needed and go to tractor Supply or Ace Hardware and get grade 8 bolts.
Sorry my comments were a carry over from another thread.
It was pointed out to me that a 1/2 inch stud calls for significantly more torque than a bolt of same. I was just curious what others do. As I said before
I am following your build to learn. A member had a head gasket failure and he was asking for potential causes and bolt torque came up. Was not criticizing you if I came across that way.
