Still hoping Dino might be able to shed some light on my question about the 753941 camshaft? ..
I think that cam would be way too big for a 4.0 given that you're limited to a maximum of 5250rpm. It'll also be a dog at low rpm given that the stock CR is only 8.8:1. The 753941 would do much better in a high compression stroker (10.0-10.5:1).
I suggest you go for the 753905 cam and increase the CR to 9.5:1 by using the Mopar Performance 4529242 head gasket, mill 0.010" from the head, and mill 0.020" from the block. Use the aforementioned springs/retainers/locks and add 0.030" shims (Crane shim kit 99179-1) under the rocker arm bridges to correct the lifter preload.
Port the head using my write-up as a guide and you'll be just about done with the internals.
