Valve cover gaskets replacement

Hi! I have been doing a lot of work to my car listed above. Thanks to the mechanics and this website, I’ve gotten a lot of help with my repairs. I’ve watched a lot of how to videos on replacing the valve cover gaskets but I can’t find a video of my year. The newer years have more room to replace the gaskets. This job is pretty straight forward but I have two issues: The left side appears I need to remove the brake booster to get the cover off and right side I can’t get to bottom rear bolt on cover (heater core housing in the way). Any help or advice is greatly appreciated!
