The .0015" is a bit on the tight side considering you plan some nitrous use. If it was mine I'd get the +.001" clearance set and use just 1/2 of it, this would put you at .002"-.0025" clearance.
Splitting sets to fine tune clearance is quite common in the high performance and race engine scene, so don't de worried about it.
Be honest with yourself about that nitrous amount.....the power gets addictive and often leads to stepping it up....more than a few engines have been toasted due to the owners upping the jetting to the max the solenoid will flow.
If you're the type that this would be a possibility, then use the full +.001" set(actually, it would be a .009" under, or sometimes called a .010x")….and makes sure you've got the added RING gap to also handle more nitrous.
If using stock rods, even with ARP bolts, don't run them on the tight side, get the additional oversize there for sure if it measures out tight. Slightly tight a thr rod will only ba acceptable with a race type rod with 7/16" capscrews.
