How bad is it?

Well did you get it all figured out !!!!..bolts could be a problem..not grade but like you said..too long..not in overall length,but in unthreaded portion ..the longer overall the bolt is the longer the unthreaded part is from under the head to where the thread starts..this can bottom out and not tighten on the manifold ..some bolts are made threaded all the way to under the head,but they are hard to come by ..I had to just go to shorter bolts,because the flanges on a eddie[.replaced] are thicker than a weind and the bolts wouldn't tighten the man tight..except out on the corners where its a lot thicker..if one wasnt observant,it would be easy to tighten up and not realize the gap wasn't closed and under 35lbs..bolts could be at 35 pounds but not the manifold..j
