That's a new one.
As far as head retention
goes, I'm not sure if there is really too much of a good thing, but things like using wheat or crystal malts would contribute.
As far as it actually being overcarbonated for the particular style, it could be one of three things that I can think of. Firstly, adding too much priming sugar, but I assume you're using a calculator, e.g. this
. Secondly, if your beer isn't completely attenuated prior to bottling, fermentation could continue and overcarbonate; the hydrometer is your friend here, of course, since the reading needs to be stable prior to bottling. Thirdly, it could be an infection/sanitation issue, since infections can lead to "gushers"/excess carbonation.
