Knurl guide? Some engines with cast in guides-some Chevy- knurling is practical way to do lower cost valve grind job. Ford had oversize valve stems on replacement valves more available than GMs- $14.00 to $20.00 a valve compared to $3.00 a knurled guide was the advantage. Dodge hemis and VW beetle engines had easier to replace valve guides-Half knurling was only a oil control measure for valve job. Some Tecumseh engines didn't have replaceable valve guides like Briggs-knurling was the practical option. RN.
