I run a 195 because I have a newer Magnum motor made to run in that range.
The pic I posted is a Magnum motor dressed as an LA.
Could be off base on it, but I feel 195 is a bit on the hot side for the older motors with larger bearing clearances, and some feel that the hotter they run the cleaner they run.

Obviously just one person's opinion.:D
