shooting coolant out of reservoir/defunct heater

Everything was machined, I used a Felpro aftermarket headgasket. I don't get why the bhg-like symptoms didn't appear until now (it was replaced back in Oct.). Its an N/A, so I used the original bolts. I think 85 ft*lb (not ft/lb!) is too much for the stock bolts. I told my mechanic to torque it to 70 ft*lb as recommended, but even if he did use the factory specs I don't think it would blow again after 800 miles (it took 125k to blow the first time!).

It's also strange that I'm not getting the waterfall sound behind the dash when cold. Makes me wonder if there is indeed trapped air. Could it be a coincidence that both radiator caps crapped out (one is a Toyota the other one is an aftermarket, but neither new)?

I know the defunct heater is related. Any ideas?
