Default Re: Header bolts - what type and size

I have new headers being shipped to me this week, so I can check the bolts for you when they arrive. I can tell you that they are metric and the length of the bolt is very very important. Go too short and you will strip the aluminum heads. Go too long and they will also strip the threads in the aluminum before headers are tight. It's best to use the bolts made for the brand of header you are going to use.
