use zddp oil additive.

Some engines tend to make more valve train noise than others. Not sure why. maybe push rod length, lifter bore angle and roundness, valve guides and seats, ect.

Aggressive lift rates, like on XE cams can only make valve train noise worst. Plus, no doubt aggressive lifts will wear the lobe quicker or will make a lobe go flat easier if there are any other issues. (wrong oil, bad break in, lift alignment, ect).

So it may be ok or it may not. However, the chances go up for noise and lobe wear with aggressive lift rates.
