I would not consider beehives unless you use HR lifters.

You only need to increase the seat pressure as a hybrid if you want to run a lot of lash, more lash, more seat pressure, and your not going to want to run much lash with that XFI cam, it is too aggressive off the seat, the lash ramp on the closing side is pretty short, and not that big of a cam. You loose duration with more lash.

On one of my hybrids with iron heads I run 150 on the seat and just over 410 over the nose (413 spring rate) .630”lift. I zero lash the intakes when cold, just have some friction when you turn the pushrods, then I run .005” lash on the exhausts. It tightens up some when hot. It operated very quietly, you can not tell it has a roller cam in it, the red line on it is 7500. It is pretty high strung, and a much less aggressive cam profile than an XFI.

For that small XFI cam I would shoot for 160 lbs and just under 400 over the nose and 1.65 rocker as a hybrid, and use a dual spring. With HR lifters you would be happier with beehives.
