Many of the vehicles that I have worked on that had headers had some of the issues that I mentioned. I have also encountered
starter heat soak issues. In those cases the installation of a mini-starter cured the problem. It's about personal taste. Quality, price & design are also factors to be considered. Many aftermarket parts don't meet standards, headers are only one of them.
