Can a 400BBM w/cheap aluminum heads compete/dominate against the street LS?

Your questions are to my thought processes......well.........frustrating.

OOTB or ported.....potentially yes and then again no.

How many aluminum heads are out there? How is it possible to answer for all of them? The iron heads we have ported can be out flowed by any big block aluminum head we have ported. We have unwelded and non-epoxied RPM and Stealth test ports that flow 350 cfm.
