After 3 or 4 times, and topping off the reservoir, I could only push it in about an 1/8 of an inch, which is what the instructions said is supposed to happen. Now that I'm thinking about, maybe that suggests that there isn't an internal leak?
When I was building the car I had asked someone at Factory Five what MC to use, and they told me to use one from an 87-93 mustang. You're probably right, I probably should have used one with a larger bore.
I have never heard of bleeding a MC with the ports plugged. Over the past 50 years all the MCs I have purchased came with fittings to put in the ports with clear tubing that you loop back into the reservoir. You then pump the MC until there are no bubbles. It will take a lot more than 3 or 4 times to get all the air out. Plus you need to stroke the piston it's full travel.

Note: you can you a couple of pieces of brake line to loop back into the reservoira.
