Custom thicknesses available upon request.
These are special order please allow 1-2 weeks delivery within the US.
NOTE: At KO Racing we recommend ordering a gasket thickness that will maintain .040-.045" clearance from the top of the piston to the bottom of the cylinder head. For Example: If you measure the piston at TDC on your short block and it is +.006" out of the bore - order a gasket between .046 and .051" thick to maintain clearance.
