I too have tried the gravity bleed method. Fluid did drain out. Just slowly. I was desperate (a newb) as it felt like there was still air in the system. I would think that pressure bleeding is the best/most convenient way. Now that I have a spare reservoir cap, I can make my own pressure bleeder. AFAIK, the brake pressure regulator doesn't "kick in" until vehicle is at a certain angle. P 47.9 Bentley specifies removing the nuts holding regulator down, and tilting to 30* when testing it. I would think that in theory, it shouldn't restrict bleeding. And in passing, I've always found it interesting that there is mention of a "lever" on pressure regulator. P 47.8 says it should be pushed in direction or rear axle. I have seen similar mention of this in Haynes too. (air cooled version). I don't see one on my '81 or on the one I removed from my '85. P 47.8 also says to "disconnect vacuum hose/check valve from brake booster prior to bleeding". Hmmm..... Never knew that was needed.
