"So the cams from an overhead cam engine B21-on, are identical to and interchangeable with the B20 and earlier engine cams..."

Not even slightly.

The pushrod cam has three bearing surfaces, the OHC style has five.

The pushrod cam has a drive gear for the oil pump 'n distributor, the OHC style does not.

The pushrod cam was driven by a big mutha gear, secured by a big mutha nut, the OHC style is driven by a sprocket, secured by a bolt.

On the other hand, they both have eight lobes......

Oh, wait — you're joking, right?
