Wikipedia is really not a good source! They are very famous for their inaccuracies.

The colloquial usage of OHV v OHC is as it was described in Wikipedia. Technically of course the valves are over the pistons in both architectures. On a daily basis however, OHV is generally used to describe a motor w a valvetrain actuated through pushrod and rockers from an in block camshaft.
