RB's (at least in S-chassis swaps) are very difficult to burp sometimes due to the pocket of air that gets hung up by the thermostat.
I was doing some reading, and looking at the thermostat that fits my WRX and realized that they all include a tickler deal of sorts to ease air bleeding. Why don't the RB thermostats have this?
Next time I do a thermostat installation, I am going to drill a small hole 1/8 or less to help get the air out of the system. Ill bet that helps quite a bit. I have read about folks doing this on the ford forums when I searched, but anyone tried it on an RB?
