The problem seems to be that the Bolts are coming loose. It is completely normal to have to retighten the header bolts a few times after initial startup.
I used to use just Silicone ,and then gasket and silicone ,but now I use stock OEM gaskets dry and nice and tight with the metal side to the headers.
I still check for tightness often.
The huge headers and sidepipes that "hang" on those bolts are quite heavy and have good leverage on the bolts!
