You should probably mock it up before you make a decision. I used the offset lifters from IMM for one low deck build and they seemed to help a little bit but it is also another complication that you have keep track of.

This is a constant area of frustration for Mopar guys. I built myself a little tool a few years ago that shows me the relationship of the oil gallery to the holes in the lifter. I use this tool to double check if the lifters are going to work or not. I'm sure other engine builders have similar tools.
