Description
Special ground thread. High speed steel. Note: This is the large tap for the valve plugs, not the spark plug threads.
Note: We may be able to provide oversized taps and plugs if you can save an otherwise good Ghost block that has badly deteriorated valve plug threads. Contact the SGA tech folks if you have interest, but try just cleaning the existing threads first with a standard tap and then testing it with a new plug. The brass plugs are known to “shrink,” and that may be all that is wrong.
