As part of my 455 build I am installing an original 1970 W455 aluminum intake. I am having trouble locating the correct intake bolts. The manifold requires 4 short and 8 long bolts. All of the kits I have researched appear to contain just the opposite. Has anyone else had this problem and if so where did you locate the correct bolts?

 

Did you check Elderbrock? I bought mine from them, but that was years ago.

 

I measured what I needed, went to a bolt specialist company, and bought the correct length bolts and hardened washers. Doing that will not get you factory-correct fasteners, but for my application it was the easiest and least expensive way to get the look I wanted

Otherwise, Fusick Automnotive has a bolt kit that is much closer to factory appearance (IBK647 at $40).

 

Thanks guys. I think I may have found them at Oldsrocketparts com. I will follow up on this thread when I receive them . They were in stock.
