Header bolt recomendations

I used the stage 8 locking bolts on my 4.7l dakota and they worked a hell of a lot better then the stock bolts. I had header leaking issues alot till i put the stage 8 bolts in place. Has not been a problem in 2 years. So i think its fixed for good.

The bolts seem to rust off and break in stock form and thats the begining of the leaking issue
