Sure there is. I think it on the same isle as the chain stretcher.
Sorry man can't say as I heard of those either. Maybe that's what they are calling a camshaft now days.
could they mean a "pushrod actuated valve gear" (valve gear = valve train)? 
The term "valve gear" is an old term for the system that operated the valve to admit air/steam/fuel/etc....

Come on, the guy asked a legitimate question so give a real answer.
A pushrod Valve Gear is a miniature gear inside of each pushrod. I am sure that you have seen a number of post on bending pushrods with missed shifts or mechanical overevs. The aftermarket has addressed this with a new style pushrod. This has a gear actuated valve inside the pushrod to allow for beed down in a situation that would bend a normal pushrod. These are new and somewhat untested to date. I have not purchased them myself as cost is a factor. Also do not know if any sponsors carry them yet.

Do all you comedians remember that "gear" is a word with multiple meanings?
I found the likely source of Rocket-Doc's confusion on the Idaho Corvette Webpage www.idavette.net in a description of the 2001 LS6 engine.
The point is that this engine doesn’t have overhead camshafts. Rather it has “pushrod valve gear”

This new Gen III puts out 385hp at 6000 rpm and 385lbs/ft torque at 4800rpm. A dozen years of engine technology advancement gets us 10 horsepower and 15 pounds/feet torque with identical peaks. If that doesn’t seem like much, consider that improvement comes from an engine with: slightly less displacement, smaller physical size, only one cam, only two valves-per-cylinder, pushrod valve gear, less weight and better fuel mileage.
