after seeing how AFR dealt with a customer in the for sale section, i would advise against them based solely on customer service.
But i agree with zracer, you'll know what suits you when you find it.

With that said, my vote goes with AFR. All the companies you have listed are top of the line head makers for LS engines, so you really can't go wrong.
there are those which are 215 cc runner. If you do a search there is a guy on ls1tech that swapped just the heads from AFRs which are a highly regarded head and picked up like 22 horse at the tire with just a head swap.
