yeahhh...there's a reason you can't find them "ANYWHERE!!!".....they don't exist because we don't have 'em. lol.

There's a camshaft in each head which push the valves open and closed. SOHC = Single OverHead Camshaft. OHV = OverHead Valve. OHV's have a single camshaft in the middle of the block and uses lifters, pushrods, and rockers to transfer motion from the camshaft to push the valves open and close.

The 4.0 SOHC has factory roller followers that fit between the cam and valves. Although they have a vague resemblance to traditional OHV rockers, the operation is different. Each follower contacts the valve stem on one end and the hydraulic tappet on the other with the cam roller in the center.

This is a picture of a Modular follower but the 4.0L part is similar:
