Those options are all wrong imo for your desired setup. With a ported head you don’t need quite as much duration to achieve the same effect. If you were not thrilled with the old cam in the 6.0 then you need to consider that. Of the cams you mentioned the first two wouldnt be any better and the last would be a dog down low in a 5.3

I spend most of my time driving like a normal person. I do like to pull it up to readline a handfull of times per month. I want it to be all there though when I do it!

personally, I am not a fan. They were designed in the days of small inefficient compressors and for stock like idle. They were pretty soft off the bottom also in a 5.3
ive tuned a couple and they never impressed me. Many like them, or did anyway.
Again this is just my opinion.
