ANOTHER LS3 breather question (sorry!)

Hi guys. You are probably sick of reading these posts now, but I’m a bit confused on what to do with the valve cover take offs (capped from factory) on my new crate LS3. Been searching the web for a while not and I’m more confused than when I started. It’s been fitted to a ford Capri running haltech ecu and no MAF or intake pipe, just a cone. Don’t need to Comply to any emissions regs etc.

SO, what do I do with the 2 take offs exactly in terms of routing/plumbing? PFA

Don't forget there is also a valley pan PCV or tube. Go to might mouse solutions they have some PCV diagrams and also you will need a catch can. Some of the tubes are restricted like the valley pan that is so you do not suck in oil. The hole is only .100. It is important as the valve covers are 3/8 tube no restrictor some of the valve covers might have a restrictor in it. Photo below of valley pan tube I pulled out that would go to the suction side (post TB - inside manifold - you can see the restricter). Its like a little "U" tube this is where they normally put the catch can between these two parts.
