Tim,

The direction of the helix cut(left or right) denotes which way it " loads " the
cam shaft. The Model A will load it back, the 32-48 Ford V/8 is also the same,
the 49-53 has an opposite helix and loads to the front, BUT has a thrust button
to stop the cam from screwing it self out the front cover. Even when doing a
49-53 I use a earlier gear set, works better.
