What size are the bolts on Big Block exaust manifolds. They seem to be in between normal sizes. And does any one know of a good source for these. Mat

Are you referring to the bolts that hold the pipe flange on, or the bolts that go into the head?

I am refering to the bolts that go onto the head. They are 3/8-16 threads but I dont know what the proper length is. I believe there are two different lengths also. I have access to stainless bolts in almost any size, but I need the proper length since they will be hard to cut shorter. Mat

Stainless is not that hard to cut use a new blade to start with...FRED
