[rpm07]

I had the same problem on my 03. I had to take off the manifold to get the bolt out. I also found out it happens alot so I said screw it and put a set of Edelbrock headers on. direct bolt up. Also if you are going to take the manifold off get the motor warm the bolts come out easier. I was told from some peolpe to get it warm and some to do it cold. I dont know but when it was warm they came out alot easier.
