valve stem height - need some help

When you’re reworking heads for improved flow, many times there is no consideration made for the valve tip heights.
You position the valve depth in the chamber that flows best, and the tip height is what it is.

I just assembled a set of fairly expensive CNC ported Dart heads, that came from a very well respected porting service.
The intake/exhaust tip heights were off about .040-.050 from each other.
The intake seats were sunk a bit to gain more top angle length so there would be a better transition into the chamber, which results in the tips being higher.
That’s just how it is.

From another head porting service:
“The intake stem heights are equalized and the exhaust valve stem heights are equalized. ”

Notice they don’t say the intake and exhaust are equal height...... to each other.
