M7 Cheater Head

[dezmitchell]

Does anybody have any opinions on a good head for a 06 M7.

Looking for something that wont sacrifice the ability to fun reg fuel as well as reliability.

Any info/previous experance would rock.

Thanks.

i ride at 2200ft around edmonton area and i ride mcbride about once a month so i was a bit concerned about such a change and i dont wan2 change domes everytime i go to the mountains ......and did you notice quite a significant improvement over stock? worth the 500 bean

yes works great and rkt set the comp ratio for where you ride and works just as good in mcbride,he set mine 13.2:1 and run 91 oct,as for the ass dyno feels like it has more bottom and mid and faster up top
