With my slant 6 I used Lucas Hot Rod and Classic 10w/30. It has 2400PPM zddp already in it. I also used zddp paste on the cam and lifters. Only tips other than that are make SURE the lifters spin. That's the most important thing. I also rip it up on break in. I vary between 2500 and 4500 for about 15-20 minutes. Splash lube is what you want and it won't happen at idle to 1500. The last guy who asked my recommendation for cam break in procedure went home an hour later and cranked it up and let it idle for 20 minutes. Some people you just cannot get through to. But the lifters spinning is the most important thing.
