4 branch exhaust manifold questions

Well done Howard, that looks really good and 'the part'. You've worked out that the middle stud is redundant and cut off flush or the tapped block hole filled with a sealed grub screw. I find that instead of trying to get full sized 1/4BSF nuts on it is easier to use M5 brass nuts tapped out to 1/4BSF - the spanners or socket are that much slimmer!
