I talked with Marty today and there have been issues with the headers. They had to mod them just to get them on as they didn't fit right. Then the gaskets keep leaking. I read the other threads about using the OEM along with the gaskets from Bassani. However the other problem is the bassani's are oval and the stock ones are round (not sure about the shapes, just that the shapes are different). Has anyone else had problems with the bassanis not going on correctly or problems with the gaskets?
