Troubleshooting Head Components

The exhaust side runs hotter on any engine. The best thing you can do is to make sure there are no restrictions in the exhaust, the freer flowing it can be the better. Also make sure you're not running too lean.
Allow me to rephrase. I understand the exhaust side runs hotter, but from the research I've made, mine has been running hotter than usual. Before upgrading the radiator and the fan, I was regularly on the verge of overheating. So far, I've only had one instance in the summer where I was getting into the danger zone for temps. Are there any threads on the forum you would recommend that would suggest upgrading the stock exhaust manifold?
