just thought i would ad my 2 cents to this convo.... although the number of pistons (and all associated gear) in the VH is 1/3 more than the VG, the actualy material in the block and head is not quite 1/3 more. one has to consider that there is material on either side of the first/last cylinders. so a more accurate figure would be 1/4 more or so. just thought i would stir up the stew a bit more
