Custom head gasket scan and drawing coordination

Specification Review decision points

1. Requested parameters

   State bore diameter, thickness with units, layer count, hole pattern, material and whether a physical scan or CAD drawing will define the custom head gasket outline. Units must appear on the RFQ so quotes stay comparable across suppliers.

2. Supplier response

   Ask the supplier to identify model, revision, measurement convention and every dimensional deviation against the submitted scan or drawing. Request a written packing list when the offer is framed as a kit rather than a single sealing sheet.

3. Evidence scope

   Match drawings and material declarations to the actual gasket and quoting entity. Do not treat a marketing photo of a related MLS sheet as the custom part file. Thickness figures without the measurement convention are incomplete for comparison.

4. Unresolved points

   Record missing thickness conventions, open coolant-hole questions and kit-content gaps before approving a sample or production order. New versus remanufactured condition, kit versus individual seals, and sample-versus-batch acceptance stay listed until the supplier writes them down.

When two custom constructions are offered, ask each plant for bore openings, hole pattern, layer count, thickness convention, material declaration and whether companion seals are inside the quoted package. Missing files stay open; they are not replaced with a percentage savings story or a borrowed workshop poster.
