Zeke,
Once again thanks for the advise and the extra effort.
I've got a set of 66000-12 from Crower. I was not aware of the hi lube 66000X3-12.
I'll e.mail tech and see if I can return the lifters and get the hi-lube ones. I've also determined to use Valvoline VR-1 racing oil, which has a large amount of ZDDP, from now on, and put a can of GM EOS in during break in.
It sure would have been nice if the Crower would have included this kind of information in the first place, it was available from their tech department but not in the box with the cam.
Oh well, I guess we live and learn.
Thanks for your expertise and your information.
