I'm planning to leave the baffles in my valve covers, weld one -10 male fitting in each, where the stock PCV/breathers are, and run -10 lines to a greddy/whatever catch can w/ an open breather on it. I've seen some run as small as -6 and as large as -12(powerhouse kit). is -12 really necessary or do I risk not venting all crankcase pressure and possibly having ring sealing/main seal retention issues? I just want to run the -10s because they're a little easier to bend/route. Thanks
