I am about to do the thermostat upgrade with the 1/4" spacer which requires the removal of the thermostat housing studs from the head. I pulled the housing and I have been spraying PB Blaster on the studs for the last 2 days. Now I have cold feet. I have very limited access over the studs so if I break one when trying to get it out I will be in a world of hurt trying to drill them out. I do have an nice stud puller (the kind that looks and works like a drill chuck.) It just makes me nervous when trying to remove something that have been a part of the block for 44 years. I am looking from advice from those who have gone before me. I am most concerned about downtime from sailing. I currently do not have a thermostat and I am running about 100 to 110 degrees. If I shut it off and check the temp a few min later it will be 120 degrees so that is probably closer to the actual temp.
Should I:
1. Do the job, it isn't hard and low risk of breakage.
2. Run the rest of the season and worry about the thermostat when the boat is laid up?
3. Don't worry about running too cold and be thankful I don't have the opposite problem?
