Looks like you are going for a high ZDDP product. If you have a flat tappet cam, then go that route. If' it's a roller cam, no need to go to the high price spread. I use Valvoline VR-1 in my hydraulic flat tappet cammed 440. No problems. And I've had them with other lower level ZDDP oils. Wiped out a cam and spent about $1000 to clean up that mess.
