Im not sure what its called.

I think its a pcv valve from valve cover to carb spacer.

Can I delete this and just use a breather on top of the valve cover?

It is for recirculating crankcase air, right? Unburnt fuel and carbons?

you want to keep the pcv valve functioning sucks out a bunch of stuff and one of the biggest things it prevents sludge building up, contaminating your oil up etc

Is it EGR or PVC?

It is a PCV not a PVC or an EGR. It is best to run a PCV. I would not delete it.

There is an under carb spacer block that connects to the PCV valve. The PCV valve ventilates the blow-by gases found in the crankcase, which is normal in a automotive engine, and allows them to be re-burned in the combustion process. On a street engine, unless you want to continuously wipe your engine down due to allow the oily blow-by residue coming out a breather vent, hook it back up.

OK so my issue is that i cannot find the proper gaskets for the spacer which is where the pcv hose hooked up to. I have a vacuum leak I cannot get rid of right at the intake and spacer. Can I take off the spacer to get a solid seal to my carb, then use another port on my intake for the pcv hose connection?

you could...if you wanted to but id just leave it the way it is.
those gaskets are common, not sure why there nowhere locally. but here- http://www.mustangsplus.com/xcart/19...or-Gasket.html

That looks like it, ill give it a shot. The one on there now is metal and another paper gasket under it.?

These are the only shots I have right now.

Nope,no metal, just uses 2 of those gaskets. One on top, one on bottom. Before you put it together flip thespacer upside down real quick to make sure you get good gasket coverage past
The edge of the spacer cause iv had it happen twice where it wouldn't work...more so on 4 barrel falcons though for some reason
