I have just fixed a job for a customer, which was done with a 107 kitted bike, 10.5 comp and these 583 cams. It had partially seized and was running like shyte. WAAY too much cylinder pressure. It was an unpleasant experience for both the owner and myself, costly as well. As others have suggested the early ( super early) inlet close figure means this cam is ok for what you have now ie: getting good low end in a stock low comp 96 cube motor. I would respectfully suggest that whomever told you to use those cams in a 107 is not where you should be getting your next job done.
