I would clean up the mating faces of intake and heads, then place the intake back on with just a few fasteners hand tight and no gaskets . Then measure the intake to head mating gaps both front and rear with feelers as well as the China rails. Possibly KC did not machine the intake to match the head angle. Doves are NOT perfect-but you know that already...

Pushrod alignment should be checked too. I went through this with my Dove TW long ago. If you find slant in the surfaces, give Barry the numbers and he will true the intake for you.
