Abstract
A multiple layer gasket adapted for sealing between mated surfaces of rigid members, said surfaces containing a plurality of spaced apart apertures; said 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 three loose, 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 in an engine.
