Thermostat gasket leaking AGAIN!!!!

Ok I have the same problem. Gasket failed at the film again, that stuff turns to jelly apparently on contact with coolant.

Got the aviation sealer and new FELPRO gasket. Way different than the last 2. I guess they didn’t listen the other times I asked for Felpro. I got everything cleaned up and have another question.


What size are the bolts?
I want to get new ones as these just look nasty and missing some threads.
Here’s a few pictures of what I had.
