I guess so far I've seen where people have put these heads on but it doesn't seem like I've seen where people and put them on and got their bang for their buck as in using them to their full potential. I mean if you're looking for a street brawler of some sort I'm sure there's less expensive measures... I believe if you're just looking for a cool hot rod and go to the track once in awhile for fun this could be a little Overkill.. personally I like Overkill it's just being able to afford it LOL...
