Default Piston cooling jets

Fed directly from the main oil galley, the piston-cooling oil jets bolt to the bottom of the block valley. Fabricated from tubing welded to flat plate, the ends of the squirt tubes are pinched to form an oil-misting nozzle. As you'd imagine, they just clear the piston skirt, rod, and crankshaft counterweights in the crowded Coyote crankcase. This early test block uses large, rectangular PCV vents.

What do you guys think of these? Can they get clogged? if they do get clogged does your engine get messed up?

I read that that the boss 302 engines do not have these on wiki

On boss 302 roadrunner engine "Piston-cooling jets were also deleted, which are standard in the 5.0 model.[15] Exterior changes include a high-mount intake plenum (as opposed to the standard engine's low-mounted one) with shorter runners to improve high-rpm power."

There would have to be a pretty major lack of maintenence for these to get clogged.
The filter will take out any particles large enough to clog them, and, the pressure being forced through them would keep them clear during normal operation, and maintenence.

Can't be totally sure about this, but I read somewhere that Ford has discontinued using these. Anyone know for sure?

Ford did not discontinue using them, a simple set up like this has been used for years in other applications, clogging canhappen but rarely..
