It looks like #4 is your gasket and #3 is a shim used to reduce compression. If #3 is made out of steel than it's probably a shim, if it's made out of copper than it's probably a gasket. If it's a shim than I would try it with both first, and if I wanted a little harder of a hit than I would remove #3 and use premium gas.
