ALL XE/LET heads are hand finished from the factory - but it is literally a couple minutes of work to match the large turn radius to the valve seats - and on the inlet side only.

compared to proper gasflowing, it's like a Trabant next to a Bentley - they're both technically cars, but the difference is huge.
