Pretty sure that's normal still at the 500 mile mark on a new motor.

I've had some suggest it's possibly the resurfaced fly wheel or just a bad clutch kit as it only seems to happen in that low RPM range of engagement with the fly wheel. With so many brand new parts in the engine bay I just feel like that should rule out a lot of things, but some have told me they've had plenty of brand new parts just end up as a bad egg.
