Alright here is what I came up with. These Chevrolet script valve covers have turned into a chore but so worth it on an LS motor. Seems to be holding oil now. Not blowing it out the breather and cork gaskets (also siliconed them a little) tip from @78SWB
On the passenger side I installed a -10an fitting baffle, up with 90* and hosed it up to the stock TB vac port.
Drivers side I changed the open grommet out for a baffled one. Seems to breathing a lot less oil out!
