The D heads are very similar to 20k/eg33 heads, and are pretty awesome. With port work, they will be able to flow very very well.

I think your primary issue will be the cam profiles- they have a little too much overlap for my tastes at a high pressure level. It is preference.

Another observation is that the cheap headers are very likely to crack with high EGTs. The Chinese replicas are 409 stainless if I recall, and that is not much better than mild steel as far as heat to strenght ratio. So expect to reweld them at the flanges at the least
