6T4: Follow the cam maufactures directions. I use diesel oil because of the zinc and solid lifters. I also use GM EOS assembly lube poured over the lifter side of the block and rockers before starting an engine; cam gear too.

This site http://www.micapeak.com/info/oiled.html will show which oil has the most zinc.

Good Luck
