[ihc] Piston Reply

[John Fleck <john@xxxxxxxxxxxxxxxxxxxxxx>]

Rocky,

IH older motors were the "swirl port" piston design with the dome and were
8.6 to 1 compression ration and have to have matching heads...(IE flat top
pistons will not work with dome piston heads and vice versa. The flat top
motors are 8.0 to 1
