Delete Heat, What can I take out? Options

[BPic]

I'm getting my engine ready for install and since I won't have heat, headers and no tubes in longs, what should I shouldn't I leave or bock off on the engine? Do I remove the flaps on the fan cowl? Bolch the holes at the bottom of the fan cowl? Remove the controller that moves the flaps? (IMG:style_emoticons/default/confused24.gif)
This is a 2056 with Carbs..

Thanks,

Remove the flaps between the fan shroud and the heater pieces. Leave them open, as the system was designed to have them. I remember reading something Jake wrote about how blocking them actually causes the fan to loose efficiency.

I've read this here before, and I'd like to see that info from the horse's mouth because it truly doesn't compute. Seems like an oft-repeated Old Wive's Tale to me.

How would blocking off airflow/pressure loss cause the engine to run hotter? Doing so would actually increase the delta-P across the engine, resulting in more airflow, thus a cooler engine.

I blocked off those ports on my racer's engine. Makes absolutely no common sense to leave those open to pressure loss. I also seem to recall that there was one version of the Bus that didn't have those ports at all, due to having a gas heater.

As a related aside, Chris Foley completely removes the warm-up flapper system with his remote oil cooler kit (http://www.tangerineracing.com/remotecooler.htm). Seems to me the factory bellows/flapper design is more there for faster oil warm-up than for the engine cylinders or heads (those get warmed up fast enough by the combustion process).
