If you need high, deterministic, quantifiable precision, you're probably better off reimplementing the critical blocks yourself the way you want.
Most of the default blocks will have numerous optimization for speed that can sacrifice precision. And this will actually depend on which version of the volk kernel gets selected (generic / SSE / AVX / ....) because they use different algorithm and opcodes and such. I'm pretty sure the rotator SIMD version has spurs because of the periodic renormalization process, but in any case they're like more than -130 dB down which makes them irrelevant for all but the most demanding applications.
