CC Venting?
I have read many different threads about vent/catch can set up's for twin turbo's but still don't know what will be best for my build.
I planned on running 2 -10 or -12 lines one from each valve cover to catch cans then back into the fresh air side of the turbos I could also pull from the valley cover if that is a better way?

Then the intake manifold 'sucks' the vapor out of the valley plate and filters it through a catch can. Put a check valve in the line by the manifold so boost won't pressurize the crank case.

IMO if you have a built motor with FI ring gaps you need lots of CC venting. Much more than a typical catch can can provide. I have a -10 on each valve cover to a can with a large breather on it. Before that I would always push oil out the rear main.

for sure... I pushed oil out my rear main until I added a -10 line and moroso catch can (in Bill's garage no less, lol)

Ditto, same as above. I ran my NA setup like that for years, but used just cheap 3/8 or -6 rubber line from the valve covers. With the turbo setup I have the catch can mounted by the air filter so it does pull in some of the stank haha
