not unless you replaced the crank sensor. if you did, then it needs to be set by a shop with a scan tool.

changing the gasket should not effect it at all.

re check your work for unconnected wires or vacuum leaks.

P0300 is misfiring codes. ensure the spark plugs and related componest are installed correctly and connections secure.
