I seem to remember reading Odessey batteries could be oriented any way but upside down, but remember the +6, -4 G environment this battery will live in compared to the motorcycle environment the battery was designed to live in.
Also, if the plan was to mount low & central on the firewall, consider interference with engine mount & proximity to exhaust heat sources.

I don't see a photo. But Odyssey and EarthX batteries can be mounted in any orientation. Even inverted. Even the vented version of the EarthX. I got this information straight from Odyssey and EarthX.

Example: F. Atlee Dodge has an STC battery modification for Cessna 180's placing an Odyssey (SBS-16) on the engine side of the firewall that allows any orientation.
(a few more airplanes too)

That's not what Odyssey says in their Technical Manual:

"Mounting flexibility
Installing the ODYSSEY battery in any orientation other than inverted does not affect any performance attribute."
