I'm no expert, but to me looks like similar cams and output wouldn't be to far off from each other, the xe250h has a tighter lsa and faster ramps so probably a better under the curve performance,, but I'd imagine the differences wouldn't be overly huge. I'd would go with xe250h mainly cause of the 110 lsa. There basically similar to a stock 340 cam
I'm no expert either but I would think the comp with the shorter advertised duration & narrower LSA would yield better cylinder pressure / dynamic compression all else being equal. Assuming both use the same lift point for advertised duration.
