ofA (maximumprojectionofthepistonfromthecylindersurface)
there is a matching gasket among the three available (with no
notch,onenotchortwonotches)toachieveaclearancevolume
between0.66and0.90mm.
IntheLDW1603enginestheheadgasketismadeofbre,while
intheLDW2204/2204-Tenginestheheadgasketismetal.
