APE's super state-of-the-art Serdi cylinder head machine, with triple-float head for the most accurate valve seats possible.

The Serdi uses a multi-angle carbide cutter that has the seat shape ground into it. This ensures that all angles are exactly the same - all seat widths are exactly the same. A perfect valve job.
