viper heads

[extreman1]

Any one have experience with after market heads for a viper w/bender pipes?
which one has best bang for your buck?

buddy used a speedwerx head on his viper w/aaen pipes. worked great. no problems. his had a little more power than mine with aaen pipes and stock head. so, the head seemed to do something. his revved quicker and needed a little more weight.
