There is a height difference of about 0.060" between the D44/55/Super 44/55 and S44A/S55A blocks. By changing out the crank, piston and much thicker head gasket, you convert the Super44 into a model S44A. The standard style blocks starting with a D30 have a higher deck height than D44/S44 of about 0.030". The Mc10 style blocks, 1.500" stroke, S44A/55A, 1-70/80, 1-71/81 and 1-72/82 all have the same deck height that is another 0.030" taller.
So basically two different deck heights between the standard and super 4.9 ci motors. Super models the pistons pops out about 0.020". Standard models piston sits down in the hole about 0.010". All of the 5.3 ci motors with removable heads have the same deck height, which is about 0.030" higher than standard models. Have I confused everyone yet?
