Default Crankcase Pressure and valve nubs...

Should there be any difference as to which valve nub allows crankcase pressure to vent easier than the next?

Been chasing my tail on some oil/breather problems. Have moved breathers to different nubs. Rear nubs seem to blow out less oil, but are they venting CC pressure as much as the fronts?

Or maybe the rear nubs get more filled with oil under hard accel when oil sloshes to the rear?

Our pressure should be about the same. Assuming most of us are seeing 1psi under boost (someone put a gauge on the dipstick tube next time you dyno).

Just wondering which nub is best for our breathers and if it makes a difference the way oil sloshes around inside our LS1 valvecovers.
