so i'm in the process of removing the head and would like to simplify the bay a little.
i live in a state w/o any emission inspections and was wondering what all I can delete. mostly looking at PCV just to clear up some old cracked vac lines.

There really isn't much involved with respect to the crankcase ventilation system, or vacuum components really.
If you don't have/need AC, you can probably remove the idle boost valves. They add a couple hundred rpms or so when the idle dips below a threshold.
If you think you can survive with a finicky idle when cold (especially during the colder months), and don't mind giving it gas to stay running before it warms up (or don't mind a high idle when it does warm up), you can kill the auxiliary air valve as well (under/behind the intake manifold by the battery).
There's the evap stuff below the coolant bottle that you can take out.
The hot air flapper can definitely go, along with all the vacuum hoses for actuating it.
That's really about it. A vacuum line for the hvac system / vacuum reservoir.
I'd leave the AAR alone. Idle boost valves is up to you. Definitely cleans it up without it and you should be okay (assuming you don't use AC)
As far as the crankcase goes, you could run a catch can, or just connect it straight from the valve cover to the intake manifold (got an easy port if you remove the idle boost valve hose). Get a new grommet for the valve cover while you're at it.
