If you can't find specs for those forks I would add a bit more oil than you took out because there would have been a small amount still remaining on everything.
Depending on how they feel after you reassemble them you can try different oils to fine tune them or add spacers under the cap to preload them.
The Paioli forks I shortened were super soft with the stock 7.5wt oil in them so I put 15 wt. and they feel pretty good now.
I was afraid they would bottom out with about 4" less travel than they had originally
