Having problems deciding which head i should throw on, money isnt an issue so cost doesnt matter. I just want a fun daily driver with some power but also very reliable. Can some one please break down these vtec heads for me and give me some input. (ITR, CTR, GSR, B16) those are the heads im going back in fourth with but dont wna decide untill i gather more info and specs on them also want to know if anyone out there has a similar set up and feed back would be great.And whats the difference between the CTR head &B16SIRII?
