I'm new to this whole turbo thing and wanted to get some input on a catch can setup. The car is a 2002 AP1 and mostly a show car a this point but will see some spirited driving here and there.
I'm going to color match the valve cover to the rest of the turbo kit so I'll be buying a new valve cover.

Is there an advantage to buying an AP2 valve cover if I'm going to vent with -10an fittings? (even if there is no real advantage this is probably getting done for looks)
I plan on using a schmuck built catch can and full blown intake manifold. I would like the bungs to be welded to the front of the valve cover as seen below (for aesthetics).

Any advice is greatly appreciated

 

This is done to equal the crank case pressure to atmosphere, so you aren't pressurizing the bottom end.

Any FI car with over a Bar of boost should really do some research on this topic. Its been covered a million times over, but what I stated above is the reason its done.
