Comp Cams ex275xl question

Ok guys got a question for ya, I have the Comp Cams EX275XL cam in the 440. 1.6 roller rockers, B3 geometry correcting kit and new pushrods. The thing is really running nice and strong especially when my foot is in it. At cruise speeds, say between 2000-2500rpm it has some valve train noise. From what I’ve read it’s normal due to the closing ramp on the cam and nothing to be concerned with. It also seems to have a lite exhaust pop at cruise but not like a miss, nothing you can feel, just hear. Step on or lift the throttle slightly and it’s gone. More characteristics of the cam? Or possibly just a tuning issue. I still have to check the actual rotor phasing. Just not thrilled about drilling a hole in a $50 MSD cap. Other than the little noises this thing is running like a scalded ape!
