I would say in 9 years time the build list has changed a little. For example demon carbs went under, and has only semi recently been bought by holley. We now have our own ignition line, so MSD is reserved for the "pro series" engines. little things like that. If we can pass savings into a customer by using our own ignition components, on a street dress engine, we usually take those steps after lots of longevity testing.
