Doug Herbert solid cam?

I'm thinking of replacing the MP 528 cam on my 318 with this one from Doug Herbert:

RPM Range: 2500-6600
Advertised Duration: 285/290
Duration @ .050: 230/235
Lift: .480/.495
Lobe Center:106c
Lash: .012-.012

The 528 is:
RPM Range: 2800-7000
Advertised Duration: 284/284
Duration @ .050: 241/241
Lift: .528/.528
Lobe Center:112
Lash: .028-.032


I want a little more low end and I don't really like the 112 lsa of the Mopar cam. It has a little less lift so I could mill the heads a little more without hitting the pistons. Is it worth to swap the cams?
