What does your breather system consist of now? What size are the lines off the valve covers? I’m a firm believer in letting the block breathe as much as possible. I even welded a -10an bung(baffled) at the rear of my intake to help gases escape the valley area.

Its got 10an fittings off the aluminum valve covers and was going to this catch can with 10an fittings to 1/2npt adapters.
