M1 intake and serpentine accessories

Thanks to both of you for your replies!
This is somewhat new to me. Could you explain more in detail what you mean by this, " but intended for LA front accessories and thermostat."
My plans are to use factory serpentine including the AC but running a carb.

FWIW that M1 intake that is for sale is what I was looking at. Do you believe I would be better off with a 7577 air gap?

Thanks
