A majority of people will say yes, myself include but this is almost an endless debate. I would say if you went eddie, TF, or AFR you will be getting best bang for buck. Of course I have had good luck with TF so that gets my vote.
I'm with fiveohwblow. If you have the cash and don't want to piece meal a combo the Trick flow kit is a fine way to go and will serve you well power wise for your 306. It's a thumbs up from me, quality kit !
