Just a suggestion. Do the blue spring update after the rebuilds is sucessful. Reason is, if you run into problems firing it back up, you won't have to rule out any problems that might occur with the blue spring update. Some people occasionally have issues after the blue spring update. Not saying you will. I think it is best to do pre and post fuel checks also. Good luck.Yes, we are going to do the blue spring. It looks like we are going to go ahead and stud it, so does this mean we will need updated stand pipes and dummy plugs?
