okay i have a d15b7 with a y8 head. i'm curious would i need an adjustable cam to properly fix the timming, because i heard a y8 head on a d15 will have some timing issues. its either i get the adjustable cam if its true that the y8 will give timming issues on a d15 or just buy a z6 head, unless the z6 head will have timming issues as but i doubt that. so to all the people HT.com lay down some info for me...lol

 

not sure on the exact number, but i know it is off a few degrees
