Alright after all my frustration of finding my exhaust leak, one of my bolts backed out and blew out the gasket. now the problem im having is finding the right gasket, ive got a buddy who reffered me to remflex.com says there gaskets work wonders, but thats not the issue i need to find the diameter of the block and exhaust ports in order to get the right gasket. if anyone out there has had the same issues or knows of a good gasket please inform me. the nasty noise under the hood is driving me insane. thanks
