'93 Ford 460 - 2 broken exhaust bolts (pic attached)

I have the broken passenger side one. When it heats up the leak stops so its not high on my priority list.

When I do fix it I am going to get a Thorley header kit for our rig, copper gaskets and high flow performance exhaust to help the heat escape.

Here is a link to the headers - includes cross pipe and Y pipe!
