Mine sat much longer, so that is less of an issue. Why was it parked? That can be simply not used and forgotten about, or maybe a real problem was showing and it got parked till it could be fixed.
Gas or diesel? If gas engine take out the spark plugs put a little oil in the cylinders and turn the engine by hand, ignition of please. If it turns ok then take the distributor out and spin the oil pump with a drill to get oil pressure. Take valve covers off to see if the oil is coming up to the rocker arms. Rotate the by hand again checking that all valves open and close as they should. If all is ok put valve covers back on , spark plugs back in, and one last time of spinning the oil pump, the distributor back in and start it. I should say taking the carb off and cleaning it out should be done before doing all this.
A diesel you can not spin the oil pump without cranking the engine. So I prefer to pull the injectors put some oil in the cylinders turn the engine by hand checking valves just like you did for the gas engine, then crank the engine and watch for oil pressure and oil flow up to the rocker arms. Injectors can be put back in now, and valve covers back on.
Fuel system needs to be primed and filters changed, then it should be ready to start
