The tech may be right & the new engine may very well be ok. There is a tendancy to overfill these with oil though, and with the crank in the pan, frothing can occur. Both dealers & quick lubes will fill it to "spec" w/out thinking.

The manual is pretty specific about checking oil on a level surface. Most "level" concrete is actually poured with a 1 or 2% fall to help keep water from puddeling, so I assume a garage floor or gas station pad is "level" enough. The other thing they talk about is letting it sit for 20 mins, to let it drain back down, but the HPOP still has the 1 qt reserve.

If you have oil at the top of the bulb, where the wire joins it, I'd drop a quart (fumoto valve is real help there), and check the level again. Keep an eye on it for a few weeks (couple of times a week). If the level starts to rise again you're probablly getting fuel into the oil & I'd take it back to the dealer & have them compression test the injectors. Next oil change, DIY, and put back in 13.5 qts, check it & then top if necessary.

Also, oil additives have been discussed here now & then, and its generally accepted that they are NOT a good idea with these engines. They tend to induce more foam.

Over full oil is not the only thing that causes surging, but it is one thing to check.
