I don't have experience with that specific cam, but looking at the specs it appears to be fairly close, if not a little more radical, to the cam I run:
Adv. Intake Duration | 288 |
Adv. Exhaust Duration | 300 |
Intake Duration @.050 | 214 |
Exhaust Duration @.050 | 224 |
Intake Valve Lift w/1.6 Rocker Ratio [w/1.72] | .473 [.508] |
Exhaust Valve Lift w/1.6 Rocker Ratio [w/1.72] | .497 [.534] |
Lobe Separation Angle | 112 |
Cam Type | Hydraulic Flat Tappet |
Basic Operating Range | 2800 RPM |
The tighter LSA will most likely net you less vacuum than my car produces, which is around 15 inches at idle.
My original build included a different cam:

With that cam, which has the same LSA, I had no issues to speak of with vacuum idle. I bought myself this vacuum canister anyway:

It's still mounted in my engine compartment, but I've never had to hook it up. I think it would be pretty easy to hide if you wanted to see about using it. You could mount it in the fenderwell where a lot of the emissions stuff is if you'd like to hide it, but I don't think you'd necessarily need it.
