adding a 2nd PCV valve

where I was going with this is since I am restricted to a 2bbl that additional air/fuel would be a gain & I heard something about doing this. it does sound (quite) a bit out there but I wanted to pick the brain trust. & it wasn't that I wanted to evacuate the crankcase more but to add air (& fuel) for more power. I am limited to 9-1 & race fuel is allowed so I think I'm good on detonation. RR
