My gasket that goes from the header to the Turbo has blown. The reason it has blown is because there was only two studs in there. I have ordered the riviera gasket for it, but NAPA says it is on special order. I have made a up a copper gasket from some flashing I had. My question is whether to go with that or just use some of the copper silicone. I'm tired of waiting for the shipment of the gasket. Appears from other posts I've read it can be done both ways. Just curious what everyone else's experience was.
