aussie 408 combo

Do you need to consider getting some heat into the inlet manifold? Cold starts in the middle of winter could be a *****. Use to **** me on the Melbourne winters.
I bought a M1 dual plane for this reason as it has water heating on the manifold but I've now shifted up north so this isn't a problem, so I'll probably sell it and get a chinese air gap copy from ebay.
What version of the edelbrock heads do you have?
