I ran the same comp cams in my old nova II and loved them. good sound and great performance. I ran standard comp lifters and the recomended comp springs with no issues. brad penn oil. flat tappets need lots of zinc in the oil to be happy.

Good news is you have a lot of choices. I'm currently running a full roller Crower EFI series cam set up (LM00483) and it works great. I have about 70 hours or more on the motor with no issues.
