pcv catch can or breather
I had that dilema awhile back and decided to do the LS6 PCV mod. http://www.ls1howto.com/index.php?article=18 Took a little while but glad I did it.

For a street application you deffinatley want to pull vacum at idle & low rpm's to remove the harmful gasses & vapors & a catch can is insurance against oil mist entering the intake. As Viper stated, on a race application breather will work as long as the oil is changed every few races unless Alky is the fuel, then you will need a belt driven vac pump to remove the moisture & unburnt fuel from the crankcase.

You do need some neg pressure in the engine to operate with out blowing seals, The PCV system will assist along with a Catch Can..
Breathers do work.. but can get messy... but does nothng to evaculate the gasses in the inside of the engine.
This is a debate that will go on forever..Do some research with the search...
IMO, if it is a street Car use a PCV system & Catch Can.

got a few quick questions,
-the orginal hose that came off the car, next to the intake, the ground strap. Should i keep that part, or can i just use some fuel hose?
-the hose from the front of the passenger valve cover to the TB, What exactly is that for?

2- Fresh air intake for the PCV system.
