Well, I am putting the driver side header in, and I have 2 issues, one it never tells me to put both gaskets on, but I went ahead and did that. Second, it tells me, "you will have to space the top mount away from the head with the spacer provided." Where is this spacer, and where does it go? I have looked through all of my stuff, and haven't found a spacer. Second does it go in between the header, and the block on the top front stud? I find that a little ambiguous. In the meantime, I guess I will get all the bolts started, and start breaking the passenger side loose.
