Alright so I eventually plan on going F/I but untill then I would like to have some fun before then while I'm still N/A. I was looking into some trick flow twisted heads. I'v seen some good things about them but does anyone have any experience with them? alslo would they be worth anything once I go F/I or just basically another cylinder head? Or if anyone has any other cylinder heads that will make my stay as N/A a little more fun? Or would a port benefit me more than getting any new heads?
