Yeah that's the 2.2 Pushrod.
Generally, I find the 1998-2002 2.2 litre OHV to be the tougher motor that GM put in this generation of J-Body. This engine was originally designed and applied in the chevy S10. They converted it for a FWD application, but to keep one of the cylinders from overheating issues they had to reverse the flow of coolant and that's why you see that big black coolant pipe in front of the spark plugs. This engine does not suffer from Head gasket problems that the older 2.2 had. Also, as a result of being designed for a RWD minitruck, the oil filter is located right under the fuel rail between the block and the firewall and right above the exhaust manifold flexpipe. My car stinks for a week after every oil change, lol.
The 2.4 is pretty zippy, but requires more maintenance. Like failing to keep the oil topped off runs the risk of spinning the #3 crank bearing. Not to mention that they have a nasty habit of eating a water pump every 125,000kms and it's a 1,000$ repair bill at most shops.
