And as far as Red Line are you using the "High-Performance" or "Professional-Series". I see the High-Performance is listed as high zddp content, but that seems to be unnecessary with roller lifters/cam setups

Because there are no lubrication issues with these roller cam and lifters set up? They may have rollers and that helps pain on the cam, but it is far from ideal as far as lubrication goes, otherwise we wouldnt have the cam fails that we do. Common knowledge at this point.

I'm sure when this thread was posted there only was HP redline, but for the record there is no reason to ever use professional series redline, it is over priced stuff you can find cheaper and better (moly) on any shelf. However, you cant buy what redline gives you at what redline sells it for as far as their high performance line up.
