Anybody have a suggestion on what brand to use? Is there any downside to advancing the valve timing?

 

I'm using the some brand Advanced Auto Parts carries, I think its like S.A. Gear or something. I think as long as you get a double roller you'll be fine.

Also I don;t think there anything bad about advancing the timing, its suppose to help with low end though but since these are comp controlled the gain won't be what it would be on a non comp car.

 

got mine here... http://www.socaldakota.com/ probably overkill for my truck but he had one and was already shipping me my roller rocker kit... so I went with it.
