Alright guys I wanna hear any knowledge you have on this topic and hopefully we can make a guide if it’s worth it. I’ve heard from some people it’s not worth it yet others say it is. I know the s8 heads are different them the rs6. The rs6 heads have a code but all the s8 heads I’ve seen are all just serial numbered and don’t have code number. I sent off the s8 valves to see if they could be just replaced with a ferrea rs6 kit and they said the rs6 valves are 8mm longer then s8.

Now which s8/s6 cams are people using? Intake and exhaust or just one. I’ve heard Tim used some on his rs6 build but don’t know much more then that. I’ve seen s8 dyno graphs a d it looks like you get more above 5500 rpms.

Again any info would be appreciated. Thank you
