340 exhaust manifold studs leaks coolant

Well I'll have to drain out the coolant, because the coolant really flows out.
What will happen if I did not seal the studs. I mean the passenger side is off and thats not a problem. On the other hand the drive side as you no is a pain. Should I just bite the bullet and just do it. I know I should but what if.
This is my first small block and some of the design is on this block has cause me alot of extra work compared to a big block. Live and learn
