  Seems to me the best approach is to assume that if you are careful with
your installation it will weigh what a Lyc 320 (parallel valve) weighs
firewall forward. This has been proven out by a number of flying 13B
powered aircraft. Chuck Dunlap's fine RV-6 at 1025 pounds empty is a good
example. If your airframe is designed for (or can accomodate that) then the
13B can be installed with the prop hub located in the same place it would
be if installing a Lyc. For insurance you can hold off on selecting a
battery location until after the firewall forward installation is complete
and a prelim weight and balance has been done. Fine tune the final weight
and balance with battery position.

I totally agree with Mike here. The empty weight is the bottom line!
Very few RV6's get much below 1000 pounds.

BTW the Belted Power Chev V6 RV6 comes in at 1150 pounds empty
weight by their own admission.
