did a little welding for my crank evac system on the headers and had a explosion through the headers....so i am pulling off the tunnel ram which i am resealing the valley pan gasket and i am smelling gas from under the car and is dripping out the collectors...after i pulled the tunnelram all the intake valves are wet and the only valve closed was #8 which was full of gas....do you think i blew the power valves in the carbs?...i pulled out the power valves and the rubber looks distorted....what do you think??....would this cause gas to leak out??
