I know, he's got me paranoid a bout this shit! The beast motor is no longer developed so i can't all anyone. Besides, it's not like theres much left in there from it. I've changed out all the internals im the bottom end and i'm gonna be changin the cams out of the top of it.

Too much friction or too little, and the synchros work against you. I'd still run the recommended weight of gear oil, but I'd run full-synthetic for the sake of the higher shifts.
I'd use something like BG Synchroshft or GM SynchroMesh. Plain-old Synchroshift is a synthetic blend. Synchroshift II is full-synthetic. You can probably find a BG dealer in your area, but Mach V and RoadRaceEngineering sell their stuff on-line if you can't find anyone.
I'm already using GM synchromesh.
