Are you sure its the hold down nut and not the return line? Did you clean out the holes before putting them in? Most of the time you need to pull the lines to get to the hold down nuts.

check the hold down if its tight, then you might have to pull it and clean the hole out

the bolts for the injectors can be replaced. as for the pyro best to weld it up and just drill your new hole
