If you can find the right person that knows what they are doing. Mine are getting ported right now for my G5x3 cam. Guys been working on them for a week and a half now to get them right. If you want some information on his work i can give you a number you can call and ask about them. My friend bought almost the same heads and they were flowing over 310 @ .650 lift
