Vvt lock or not

Pete - all of the modern hemi's are VVT, therefore all of the stock cams would be as well. The question is whether you need a MDS capable cam or not. Either way, here are the numbers I have; (please confirm type/usage before purchasing)

18-20 6.4 Hemi w/MDS 5037379BC
21 up 6.4 Hemi w/MDS 5038419AB
18-20 6.4 Hemi w/o MDS 05037379BC
