    Has anyone seen or know of any independent dyno test comparisons performed with the different available heads for an LS1 in a controlled condition?

    theres really been no totally controled test.
    the best heads out there are the AFRs though.

    It would be nice if some reputable facility would do this as it would put all the different "opinions" to rest all though some people might be afraid to upset certain vendors or "sponsors".
