How can I tell if I have a cold air sump?

I have an angle valve, light case, narrow deck 200 horse Lycoming IO360-A1A with horizontal induction (forward facing), and I need to know which Vetterman exhaust will fit it. When I emailed Vans support, they gave me a part number, assuming I have a cold air sump (which I do not know whether I do). Here's the exhaust part I received: EA EXHCO 7/7A IO-360. Thank you!

P.S. the engine came off of a Mooney, and has not been modified.

Mine is PV IO360 so an inch narrower than the AV IO360's. Here are picture of the setup I have on my 7 for one example.

In these pics you can see that the sump is divided into upper and lower cavities. The oil in the top and the air passes lower outside of the upper oil camber instead of thru it.

I talked to Clint at Vetterman and because of less space in the smooth cowl with the Horz induction he recommended the 4-pipe exhaust. The sniffle valve is a bit close to the exhaust but other than that the fit is great.

An unmodified sump off a Mooney is NOT a cold air sump.
 
Best to call Clint and get the answer from him versus getting it from him through Vans.
 
There are no Lycoming factory cold air sumps (though I did hear recently that they were thinking about making one). Cold sumps like the Superior ones have an intake section that bolts to the sump, so its intake pipes are completely divorced from the sump.
 
Ok, so who has measurements of intake air temperature rise, sump in vs sump out?

That would define "cold air sump", not appearance.

Uh, lets not muddy the waters. The OPs issue is physical clearance, not empirical testing for performance purposes.
 
Yep not a cold air sump. A cold air sump is not part of the sump at all. It is a separate intake manifold that nest's under the oil sump. The intake runners to each cylinder never go in/near the oil sump.

Why have hot intake? A warm Carb avoids Carb ice. Lycs are less prone to Carb ice to Continentals, some of which have cold intake plenums. Fuel injection not an issue. Lycoming stuck with the warm intake for FI because it is compact and works.
