Like the title say's. I am having this guy build me a set of header's or actually I WILL have this guy make them. For any of you here local to me he built the header's on Jeff Nasier car. Or least that is what I am told. See what I have is 1 7\8 to 2" with 3" collector. What we are going to go to is some thing like 2 1\8" to a 4" collector. But he need's my block and at least one head. BUT like every one knows my head's are being hand portered and are still at that guy's shop. SOOOOOO I need at least one GM 18* head. It can be blowed up head or better yet it can be a bear casting. I just need some thing he can bolt up to the block. So if any one know's of some who want's to get rid of a crack(BOAT ANCHOR)head let me know.
