It works but it lowers the compression like .5 or something like that.
It works but it is not a .5 decrease in compression. Most of the compression difference between the 04/05 models to the 06-09 models is from the short rod used in the 06+ cranks. I'd say about .1+ loss due from the head. IMO.
Is there really going to be a performance increase from the different porting though? I have my doubts...
