I have found that on the inlet side on many heads that the inlet flow is best when the angles are left sharp, not radiused. And yes, a micro boring tool is quicker than grinding and would be ideal.

if you do the 45 deg contact face first the top cut will often go right thru it as shown; it helps sometimes to do the top cut first. <DD>Forming a 20 deg top cut with a Neway cutter.
