Only way to know is to check, really. Depends how bad and how long it's overheated (assuming it did at all), and other factors. If you can confirm the gasket is bad, it's going to get opened up regardless, and those things will be checked by anyone worth trusting to do the jobf***, I guess so... Have to start making sure I'm doing a better job at that. But since I've never seen the temperature gauge get to overheating temps, do you think the head and block are still fine?
Since you stated a specific temp of 194, I assume you have a gauge plugged in?
