No heat cross over = longer warm up time. IMO, big freakin deal. The least of your problems/woories.
I have a Edelbrocks heads & Air Gap on my Cuda/360. When it gets cold out, it just takes alittle while longer to warm up. The truly hard part of it all is the open air cleaner suckin in cold ait. It closes the choke down over and over again.
A regular air cleaner fixed that problem along with a choke stove being hooked up.
