I checked the fuel pressure and it was at 6 pounds pressure. The reason I wondered is because when I first tried to start the motor after I rebuilt it the carb ( brand new) was plugged as I was trying to break in the cam. I since returned that carb because of other issues too. With this new carb the secondary’s weren’t working. Diaframe had collapsed. I don’t know if it was the multiple back fire. Both carb were Holley 600 with vacuum secondary’s. To be honest I’ve had nothing but bad luck with Holley carbs. That’s why I wanted to check the fuel pressure.
As for the runner gasket on the fire wall I’ll take a look

Sounds normal.

If your car should have a vented gas cap and it doesn't the gas tank and lines will become pressurized to a point where the gas tank can become ballooned this kind of pressure will let fuel find a weak point in the system.
