How? A compression test will not reveal a tiny leak which is plenty to pump up the cooling system with air. I had this exact same problem with my 85 sunroof GL. Got progressively worse because air in the system continues to overheat stuff. Eventually it got so bad I had to admit it was the heads.

The cooling system runs pressurized so any leaks will not allow air to enter but instead create a leak of antifreeze on the ground.

Betcha a nickel its the heads.
