I wouldn't port and polish a head onthese cars unless I was boosting the car. You can port it stock tb I just don't the worth in it to make power NA when it will b easier/cheaper/more fun to boost it.

To be quite blunt, a port and polish is not very effective in the Cobalt, especially the L61.

A port and polish job usually yields better gains on higher displacement engines that have more cylinders than we do.

Money better spent on boost.
