Probably from the 4bbl carb and intake, and the adjustable rockers. It looks a bit cobbled up what with the blue timing cover and plain-jane 1965 valve covers. Need to see the pistons to verify Commando status.
I believe it is a commando engine based on the intake and rockers. I cannot say for certain what pistons it has in it, so I cannot guarantee that it is a commando engine.
