For stock cams and valve springs, I use the moly paste on the lobes and lifter faces, of course, along with CompCams #159 break-in additive. Then run the engine between 1500 and 2000 RPM for 20-30 minutes to mate the lifters to the cam. (Continually varying the RPM lets the crank and rods slosh oil on different parts of the cam.)

After that, change the oil and you should be good to go. I have used regular 10W-30 oil with stock cams, and even mild performance cams and valve springs (with slower old school ramps like Summit Racing cams). But you can get a little more insurance with Valvoline Racing 10W-30 which has higher amounts of zinc and phosphate than most regular oils.
