SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

when i researched the cam that was in it i found this:
COMP Cams 20-212-2 COMP Cams High Energy Camshafts | Summit Racing
and there is a XE version of it
DODGE COMP Cams 20-223-3 COMP Cams Xtreme Energy Camshafts | Summit Racing
however i couldnt see a XE stamping


* i just dont go down the rabbit hole of having this heads "rebuild" with valve job, springs , guides etc at that point i spend 650$
the 454/454 268 cam is more reasonable of the two, but i think that there's better options in that lift and duration that are split pattern. the 20-233-3 is wayy big for the cubes and compression.

and no matter what you choose, you're more than likely going to need springs to match the lift. so be ready for that.
