Pushrod motors and ohc motors have OHV - overhead valves duh!
Yet another classic schoolboy error. OHC motors are not called OHV. Lets simplify things for you slim :-
Valves at the top of the cylinder head = OHV
(Thats Overhead Valves)
Camshaft at the top of the head = OHC
(Thats Overhead Cam)
Hope that helps you understand
