3rd weekend doing my project car.
I fear the main
gasket between both engine parts was
leaking...
Once the engine head cover came off, We tried to unscrew the screws.
TWO of the 10 or 8 Head Bolts are striped. Probably previous owner...
In autozone and advanced auto. They said that there is no metric key for those screws. So they gave me a T50 hex key. It does fit but gives a bit of play. Which in turn helped us strip these messed up bolts even further.

Are these bolts metric?
Is there any cheap and ez way to pull them out?
