Align the headers onto the bolt hole on the back of the driver side header. There are two sets of bolt holes that you can use. If I remember correctly, my MACs used the outside holes. See if that helps.

You should have a pair of identical bolt holes at each end of the block. Some headers use the inner pair, some use the outer pair. It sounds like you are either trying to use the wrong bolt hole or there is a busted bolt inside of it.

Nah, I know what you are talking about, my headers had that on them, just had to line up a gasket to the header, mark where the whole is and drill it out.
