The small port Commando shares the same chamber, exhaust port, intake bowl and short turn.
The difference is the intake runner. The pushrod pinch on the small port is .780" wide compared
to the LP at 1.018". The LP also has had the intrusive boss for the Magnum studs omitted from
their port core, even though it can be ground entirely away on the small port head.
