Being a turbo car I'd be really careful about wall thickness on the manifold. I hit some really high EGT's on the XR. I had a lot of problems cracking my header until I finally replaced the weak link with a 1/8" sidewall stainless tube.
I'd say put a little more work into the manifold to smooth it out and get your engine built. Worst case, it cracks and it gives oyu the opportunity to get it done right.
As for the rest of the porting, I know Dale Engineering does good work but not sure on a price. Just call around and see who meets your quality/price ratio. And for heavens sake get that engine finished ;-).
