Cross ram intakes on a small block

I have ran mine with both a dual fitech EFI system, and currently with 2 quick fuel 450s, it runs incredibly well. It is slightly cold blooded, it tends to run a bit rich at cold start, even without chokes, due to the fuel puddling until it gets a little heat in it. Just keep the idle speed up for a minute, and all is well. My engine is a 410" R block with untouched edelbrock heads, it was a Chrysler "crate motor" originally equipped with a six pack setup.
