A multiple layer gasket adapted for sealing between mated surfaces of rig id members, said surfaces containing a plurality of spaced apart apertures; sai d gasket provided in kit form for use by aftermarket racing engine builders. In one preferred embodiment, the kit comprises a combustion gasket, and includes at least thr ee lose, unriveted combustion gasket layers. All three layers contain combustion apertures but only the outer layers include fluid apertures. A center layer is designed as a fluid flow-metering layer of the gasket, and includes stenciled cutouts for the fluid apertures, the center layer being adapted for alignment with at least a portion of the first or top layer. Specific locations and shapes of apertures in the center layer are to be created in the field (i:e. at racing site). Finally, in one preferred embodiment, the layers may be doweled to be more easily mated together during installation i n an engine.
