This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match. \u003cp\u003e\u003c\/p\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin: 7.5pt 0in; line-height: normal;\"\u003e\u003cspan style=\"font-size: 10pt; font-family: Arial, sans-serif;\"\u003e\u003cbr\u003eUsing CBN or Diamond tooling the head is given a new surface.
